ive had one all my life its a must when traveling. love those lot lizards. got a 3 beam yagi at the house, talk skip all over, got someone in england last year.i got a extra if you want to pay shipping
I have some cheap Uniden one I got for like $25 off Amazon. During my maiden voyage trip ~a year ago (has it been that long already?) I had it on most of the time. Lots of banter but it DID help me avoid running over an "alligator" (blown up tire in the road). That was basically my first time driving the bus and I was paying more attention to the gauges and every noise I heard than the road! I was also warned about a few speed traps but that was irrelevant because the limit was 70 and I was chugging along at 65.
I might buy a CB when I go to Texas to pick up Texas. I have an Amateur Radio License(Ham Radio) and am taking a 75 watt 2 meter radio with me. 75 watts goes a lot farther than 4 watts with a CB and I'm legal.
CB is right, the cell phone has taken over, now hand held two way radios work great car to car or bus to bus...and are cheap/mobile and can be helpful when spotting the bus parking or backing up (never be between bus and anything solid)
Coming back from Tennessee on I40, I had no cell coverage through much of Oklahoma with Verizon.
