I installed a CB. Mainly for nostalgia. I grew up with them and we always had them in our cars through the 70's and 80's. Not so much in the 90's I guess. I remember when you needed a license to actually transmit. I was working at a lumber mill when in high school (mid 70's) and some of us were sitting in a guy's truck and he had a CB. I got ready to press the transmit button to say "Breaker, Breaker" and he was like "No, don't. I still don't have my license". We were like "Who is going to know?" but he wouldn't transmit.
It will be handy if I ever do go off road. Plus I have one in my FJ40 and me and the wife sometimes take both vehicles to a car show, and we chat on the CBs while driving and not be using the phone.
