First trail GMRS use and man, do I prefer that over CB. Still have the CB installed in the Jeep as it will be a secondary form of comms for others that haven't seen the light yet. Running trails in Moab. Ran Elephant hill yesterday and on the way out, the team leader was well over 5 miles out and some generous but not too heavy terrain between us and we were talking back an forth as if we were standing next to each other. Oh yeah!
