CB can be great for some of the same reasons people aren't liking it now. Fewer people on the band, so great if you're with a group and want to be able to communicate without a bunch of interruptions, and almost everyone has an old CB in the basement, garage, storage, etc. Or.. can get a small uniden or midland cheap. My slip-seat rig is just a tiny Uniden with an external speaker strapped to it, and most trucks have 12v lugs on the dash just for that sort of thing.
I'm ok with FRS/GMRS, and they've loosened up a bit on the latter, which I believe is good.
I'm a tech-level ham, and have a 2m/70cm rig in my little car. I rarely use it these days, as I know nobody within range, and I'm not good at seeking out people... I'm with Bob on the introversion thing... but we have 3 truck stops within a few miles of here, so a CB can definitely come in handy.
