Yeah, they were handy in weather like we are having now. We drove from Ohio to FT Meade, MD trying to out run one storm, only to run into one that hadn't developed until we were on the road and still got hit with the one behind us. Those CB's came in handy. The truckers could hear me calling the DH, same for him, so he relayed back and forth so we knew each other was safe. Then my DH saw a car almost going into a skid and he yelled at her to get off the brake, etc. Later, she told me how he helped her not have an accident.
We might get one for the MH because they also came in handy when you were driving alone in keeping you awake. We had to drive after 11pm in 1980 because our cars were not air conditioned and it was 110 degrees (I wish I could remember what a heat wave feels like, I need to thaw out). We had fun talking to truckers until we heard two different grand chiefs of KKK. We didn't speak until we were sure they were gone. They woke all of us up talking about up coming activities.
