Hi WSDE521,
let us know what radio you have so we can give you specific tips.
I'm sure you'll be able to get up to speed quickly. I don't live near you, but I did see this ham club that might be able to help you for local info:
https://w4gs.org/
Use the map feature (on mygmrs.com) to find a local repeater like this one:
https://mygmrs.com/repeater/1675
If you live in the green circle, click the blue button on that page to request access.
You can listen in to see if there is activity by tuning into 462.550mhz (channel 15), but you will only be able to listen. to talk, you'll need to program the repeater channel using tones.
once you tell us your radio, someone will be able to tell you how to program the radio for that repeater.
take your time and read the manual.
