CBs aren't anywhere near as chatty as they used to be, even on the big roads, and you'll go for days sometimes not hearing another soul.
Though they are still very handy, as has been noted in this thread, for backcountry places like the NMW and other deep forests where there are logging trucks. They have the right of way, and will come barreling around gravel corners and catch you off-guard. Some drivers will announce their location, and it's wise to announce yours if you're in a four-wheeler.
Also has been noted and not to be underestimated, is how very handy they are for when the big road turns into a parking lot because of an accident or construction up ahead. Then the truckers will get on the CB and start chatting to drivers going the other way about what happened up ahead, how many miles long the back up is, and which lanes are moving or not.
I led a whole convoy of four-wheelers once, in Kentucky with my van, on a long detour around a eight mile backup on I-75, because someone noticed I was on my radio, was punching stuff into the GPS on my dash, and had my signal on to get off at the exit. His passenger yelled up at me "You know a way around?"
I yelled back "Yep, follow me!" All of a sudden he and a whole bunch of others were sticking their arms out the window in a "C'mon!" wave, getting off the interstate behind me, and making every turn I was. I led 'em over to and up the Dixie Highway through a mess of small towns and up past Walton into Richwood, where I could see 75 N was running smooth. I turned towards the TA then onto the ramp for the Interstate and pulled over. One by one they passed by, honking their horns, yelling out their windows "Hey man, thank you!" and "You rock!" etc. I felt like a rock star.
Besides the weather channels, which I depend on regularly, traffic jam/parking lot workarounds is one of the main reasons I keep a CB around.
I need to create a better cushion mount for it, though, because I bounce it so much on washboard and backcountry roads it keeps breaking soldered connections. Then all that works is the 7 NOAA channels.
