CB radio usage

I had a CB in my car years ago, I'm thinking about putting one in my truck. The wife wonders why, as being an amateur radio operator I already have TWO amateur rigs that can handle UHF, VHF, and HF amateur bands. She says the cab of the truck looks less like a truck and more like an airplane. (Used to fly until the health went south). One more rig wouldn't hurt. I had a sign made for the back of the fiver that gives my amateur call sign as well as the frequency I monitor, which is the VHF calling frequency of 146.520 megahertz. I also carry the ARRL Repeater Directory, which is a book of frequencies for transmit/receive machines that hear your transmission and repeat it, giving you extended range. You can get an amateur license now without learning the Morse Code, and the entry license exam is multiple choice and 35 questions.
