I stopped using CB years ago. It got to the point that you'd hear drug and prostitution solicitations whenever you were near a major city's truck stop. Also, you never knew when you'd hear a tirade or swearing over the radio when we had our grand kids in the rig.
I do have an amateur radio license, and keep a multi-band radio and antenna with me. It's nice to know we have the ability to establish communications if there is ever an emergency and we're out of cell phone range.
If we are in a caravan with someone else, we use the FRS radios which give us a range of a mile or so on flat ground. If we get separated more than that, we can use our cell phones.
