I'm movin' on up (another '70's reference?). I got me a CB & and antenna for ziltch!!! Small Uniden radio and 'new' Radio Shack antenna. I heard about 'tuning' a CB but WTH? I don't have a SWR and if I did do invite it to dinner? All I pick up is hick truck drivers from AL, FL, and GA! Has everyone gone GPS on my ass? The static now soothes my ride to and from work (no AM/FM radio). Someone help!
I don't know much about CB, but I do know that if you don't tune your antenna and your radio with the SWR meter, you run the risk of ruining the radio.

Also, "hick truck drivers" is just about all you'll get on CB. CB is a wasteland now, much like what internet chat is today. I don't know what you mean by "everyone gone GPS" on you, since GPS is for navigation, not communication. Perhaps you meant FRS (Family Radio Service) which are the handheld walkie-talkie things that a lot of people now have. If so than yes, most people are using that now.
