My friend drives a truck and told me people still use them. It's mostly truckers but there are still some four wheelers (cars) that use them. I guess here in the north east it is not that popular but in the south and mid-west it still is. I could not find a CB shop anywhere. And the only place I know that sold CB accessories is Radio Shack but they don't sell anything in the stores anymore. It is all on-line ordering.
CBs come in handy when there is traffic because not all traffic gets reported on the radio. Here are a couple of pictures of my radio and antenna set up. When you enlarge the picture of the truck you will see twin black antennas mounted on the tool box in the bed.
