Look at the repeater directory that this site provides. You can search by city. 

Not the same kind of map, but a very comprehensive listing is at repeaterbook.com.

I hold an "H" license, my wife doesn't, I do not know everything.  She thinks I am a nerd, but I am a good cook and provider so she keeps me.  Got my GMRS license this week.  I got it because on "H" bands I am a CW operator.  I don't even own a VHF or UHF radio at this time.  We are going to buy, eventually, 2 decent GMRS HTs and I would like to eventually establish a GMRS base station in our location.  I thought I might want to build a repeater, but that urge has passed.  I am in the foot print of INDY 600 so we don't really need an open repeater here.  Good, saves me money for other toys. 
I have been monitoring GMRS freqs for about a year, I feel like I know some of you already, and for the most part everyone seems to get along and are very friendly.  So I have requested access to a couple repeater systems, and await the reply patiently.  I look forward to being on the system, and being able to communicate with my wife when she is not within cell phone reach.  I am perfectly happy to be mentored on the proper protocols of GMRS use. 
I have a child living in Mooresville and one in Decatur Township (Indianapolis) and I plan on getting them to jump on the GMRS bandwagon if this works out well for my wife and I.  ?
 
 

Yeah but video killed the radio star ?

When repeaters are linked to 20 others then it almost seems like the intention is to be more social, and not so much only about short comms with family and close friends.

Absolutely, as well as bandwidth. GMRS has a very limited number of set frequencies, so proper etiquette often dictates short transmissions and like you said, short-distance communications, whereas ham radio has an incredibly wide range of available frequencies and modes across numerous bands, and covers everything from short distance simplex to global communication. Where the OP is going off the rails is by driving that overused wedge farther between ham and GMRS, as so often happens here. Truth be told, I'm sitting here listening to a couple of guys on a GMRS repeater here in SoCal who have been ragchewing for the better part of an hour.

QFT!
 
If I may add on to this (not directed to you), I am going to play both sides of this debate.  The purpose of the Amateur Radio Service (also known as "ham" radio) in the United States is to provide a hobby and public service for individuals who are interested in radio communication and electronics experimentation.  The purpose of GMRS is for short-distance two-way communications of licensees and their immediate family, for business or pleasure.  Based on the definitions provided by the FCC, the idea that GMRS is exclusively utilitarian is not an accurate, in my opinion. There is overlap because of the interest in radio communications, even though GMRS is so much more restricted in use of hardware, power and range.
I think OP is leaning more toward operating etiquette.  I could be wrong.  I like the idea of community members volunteering to make an orientation video and I like the idea of new people wanting to learn and having it as a resource.  It just needs to focus on things specific to rules, technology and equipment to help people on getting started; not opinions about behavior, use, etc.
While I occasionally violate this myself, I believe we should speak in plain English and if you are on a wide coverage area repeater, it's not a great idea to talk for hours.  I recommend against tying up the repeater and radio waves for 2,000 sq miles or more for hours a day, several days a week, is kind of greedy. 
That said, it's up to the operator to decide what lingo, habits, and method they use on the service.  As mentioned, the purpose of GMRS is for short-distance two-way communications to ease the activities of licensees and their immediate family.  If that means rag-chewing, that is up to the operators involved.  It's not really up to any one of us to tell anyone else how to use their radio/license. 
As far as repeaters go, the owner doesn't own the airwaves, but they own the hardware and can set the rules for sharing, if they want to share at all.

I would hazard a guess here that the "awful habits" brush you paint the general ham radio community with is that hams tend to talk more, and that "awful habit" doesn't fit with the GMRS service. Ragchewing on a GMRS repeater is probably not part of the use case for GMRS, but the reality is that it happens. Remember that they are two different services, with at times completely different use cases. As a GMRS user, I keep my transmissions short and sweet, usually on a repeater that I am a paid user of. As a ham, my ham friends and I carry on discussions on my repeater that last quite a while. I have no intention of unlearning anything. What I do is treat each radio service with common sense, and use each one for what it's pretty much intended for, paying special attention to the rules and guidelines of the repeater owner. There are GMRS people here who cannot stand hams, and there are hams here who have a hard time with GMRS folks. Then there are those of us in the middle with dual citizenship who can't quite figure out why either side is sniping at the other side, and who would much rather see everyone play nice. 

As a "new user", I could not agree more.

Hello GMRS "gang",
After a few postings and reflection, it is clear that GMRS owners need to make an orientation video, and/or hold a group zoom for new users before allowing access. This will be my approach 100%. In this meeting or video, politely addressing operational guidelines and expectations up front would really help! Because new users have no idea what to do, and seasoned and fresh "hammy's" are already going down the wrong path, sound mentorship is the answer. Not a rigorous military drill set, but a practical and open discussion. New users WANT to know what to do, and many "hams" think they know what to do. It is an unhealthy combo for sure. It's about getting along, sharing the resource, and not making the repeater owner want to get two sticks and gouge their eardrums out...

The Technician license is focused on regulations with just a touch of theory. This is to ensure you don't cause interference with others or misuse the privileges.
You get more radio theory/practice (circuits) at the General level, and a lot more at Extra level exam.
I started as a "no-good" (no-code) Tech when they created the VHF/UHF-only option decades ago. Lockheed (Sunnyvale) radio club had their own repeater, and membership to get auto-patch (telephone linking) was much cheaper than a cell-phone at the time.
When they finally dropped the code requirement a decade or so ago, I spent two weeks with a General class study guide. Found an on-line practice test site. Was passing all tries with 90% scores. Tried (without study) the Extra class practice exams, and managed to pass about 3 of every 4 I did. So -- that weekend I drove up the Bay area to a license session and took both tests. I felt that if I didn't pass Extra, I could study for two weeks and get the next exam session down where I lived. Passed Extra by 1 question.
There are post-2017 radios that are also NFM only... But these radios will be marked as FRS (the 2017 reorganization banned radios marked FRS/GMRS, and gave FRS the typical power of pre-2017 dual-marked bubble pack radios).
My recommendation was to remove the FRS NFM config UNLESS you have a lot of associates who are using FRS radios. If most are using licensed GMRS, stick with FM setting and put up with the slight audio quality mis-match for the rare FRS user.
Technically -- there is NO privacy for GMRS/MURS/FRS/Amateur. Setting a tone only controls who YOU HEAR (they have to be sending the same tone). Anyone with a radio that has no tones set will hear /everything/ on the frequency. "PL" ("Private Line") is Motorola marketing speak. To the rest of the world it is just CTCSS (Continuous Tone Coded Squelch System -- though newer systems also support Digital Coded Squelch). Granted, many radio programming software separates it as "CT" (send a tone) and "CTCSS" (send and receive tone).
Skip is for scanning purposes -- it says "skip this channel when scanning"
Offset is for repeaters. For GMRS it is supposed to be +5.0MHz (listen on 462, transmit on 467)
Cross mode is a confusing entry -- depending upon the programming software. Some radios can be configured to use CTCSS tone in one direction and DTC tone in the other.
As I recall, in CHIRP, "TONE" means SEND-only, "TONE SQUELCH" is SEND/RECEIVE. And to confuse matters, CHIRP uses different columns for the tone specification itself (my Amateur gear, OTOH, doesn't require first selecting mode, then picking tone -- just encode/decode [send/receive] tone columns, and if that column is set to "None" then no tone is used for that side).

Note that in your screen image, the only difference between the "FRS 1-7" and "GMRS 1-7" is the difference between NFM and FM bandwidth. 8-14 are IDENTICAL -- 0.5W ERP NFM. GMRS is permitted up to 5W on 1-7, and up to 50W on 14-22 (and repeater pairs); true FRS is limited to 2W NFM on 1-7/15-22 (and NO repeaters). If the radio can exceed 2W on any channel, or access repeaters, that radio is classified as a GMRS radio. Oh, and FRS-only radios are license free, GMRS requires a license.
The only justification (in my mind) for duplicating the FRS NFM config is that you have a lot of associates using old (pre-2017 "FRS/GMRS") radios with NFM only. Otherwise I'd just strip out the FRS configuration and stick with GMRS FM (remember 8-14 are low power NFM in both services).
