In my area the only cops who have a cb in the car are CHP. Even then it is a rare thing, mostly only the CHP DOT truck. Although many years ago a buddy and I were running down a grade listening to 19 and some trucker was asking about the "polar bear". I responded that he was at the bottom of the grade by me. Moments later he blows by me and the mic is ripped out of my hand. My buddy had taken it and he's addressing the CHP officer, something along the lines of seeing how he has an antenna for cb and more than likely the radio to go with it; why not join the conversation... CHP came back a couple of moments later saying that it was more fun to listen to us than it was to talk to us... Still a high point in my buddy's radio life...
