I stay close to home and do not have a CB in my pickup. We do have one in our semi truck that we use to haul the grain to town. It comes in handy there because everyone can get instructions from the grain terminal.
I think if I ever did start traveling I would have one. After all , if someone is saying stuff that you don't want to hear you can always just shut it off !!!
Just like the TV, the radio, the internet , or anything else.
