Just starting out with GMRS, myself. From what I have seen, and others have mentioned, I guess it depends on the area that you are in.
I am in Western Kentucky, in a very rural town. Not a lot of traffic here, unless it is that rogue radio enthusiast or the bog children (groups that go mudding in their Jeeps/ATVs). Still, I set up my family with a few radios and a base station, which was the original purpose. Still pretty cool to hear others that just want to reach out and chat.
