Go 1 county north where they won't ever shut up on the repeaters
Ok not quite, there's often down time, but man when they get a rag chew going, it GOES.
But also, "GMRS community" is a weird concept. MOST people (normal people, not weirdos on here) use GMRS as a communications method while doing a hobby, not a hobby in and of itself. So while there IS a community (check out the Utah GMRS facebook group if you're on there), it's never going to have the critical mass of "we're all radio geeks doing radio geek stuff and getting together to talk about radios as much as possible" that you will with hams.
It's kinda like wondering why there isn't more of an FRS community out there. Maybe there is, but that's not what people have FRS radios for, by and large.
