On the highway I get saved from more tickets with the CB than I do with my high end Valentine One radar detector.
A CB is only as handy as there are people to talk to. What I liked about it was that my situational awareness was always peaked. I knew to the mile marker where I was, and what was going on in front of and behind me. Without it, I tend to dope off a little on where I am (one road, no towns, fifty miles, just go).
The single trick that saved me from more tickets on two lane roads was just waving at the policeman. (foot on the brake, until we pass). He waves back and doesn't lock in my speed until it has dropped.
