I was into the CB radio thing in the late '60's - late '70's. I shot skip, did T-hunts.
Back then the CB radio was useful. When my mother moved from Los Angeles to Seattle I set up a CB in her car, cigarette lighter power, magnet antenna mount. She was alone, the truckers watched over her.
In the '80's the fad got bad, too many people, the airwaves blocked by too many transmitters. The CB radio became useless.
In the early '80's cell phones came up, CB radios were obsolete.
