A friend bought a couple of sets so we could communicate between most of the cars in our caravan to Carlisle. Worked better than grabbing a phone and looking for whom to call, plus we didn't break any hands free laws, not that we were worried.
Plus it's a lot to fun. We caravanned to Colorado years ago. We all had CB handles and fed each other crap the whole trip. Sure makes Nebraska more fun. LMAO
