I've had a CB radio since Jr. High school....had one mounted on my bicycle and went to what did they call them back in the 60'ies, "coffee breaks"? in parking lots.
I can't tout the use of them nowadays although I continue to have one in the RV as well as the "toad"....still get a kick out of listening mostly now even though much of the CB traffic is now 10 meter traffic.
I use it while traveling with others(caravans) and when I disconnect the toad and looking for a campsite within a campground or narrow road leading into a CG. If your stuck in traffic, it's generally too late to do much about it but still nice to know which lines are closed ahead or exactly what's going on causing traffic. Mostly, these circumstances amount to short distance communication and I expect nothing more!
Enjoy!!!
