In our 16 years of full-timing we've used it in only a few instances to see what the traffic hold-up was. Otherwise it gets tiresome listening to mindless chatter.
On one occasion, however, we were traveling in Los Angles on one of their multi, multi-lane highways which was packed. We need to get off but didn't know which lane to get into. Hubby got on the CB and asked for help. No answer. He asked again. No answer. I took it over and stated "Pink Bunny here. What lane should we be in to exit onto such and such". I immediately got a very nice detailed reply. :)
