cb radio?

I was kind of curious about putting in a cb radio into my car. Anyone know of where I can go to get info on this type of thing?

There's tons of info on the net as to what to look for, but I know Radio Shack and Wal-Mart both carry a good selection of CB radios and accesories. (This is assuming you live in USA, Canadian Radio Shacks don't carry CBs anymore).
