when i was an OTR ('81) trucker the CB was our cell phone. I remember talking to guys/gals for hours while the mile melted by especially late at night when you are tired but need to keep going.
Yes there was some foul language at time but for the most part the convo was traffic, 4 wheelers, and truck stops with the best apple pie, The flying J out side Atalanta on I-85 :) or where the best showers are etc.
Now a days you have to pry info out of them.. On a trip to Florida in March 2016 I did hear guy heading north on I-95 shout out "hey south bound not sure why the hell the traffice is stopping, din't see a wreck." and that was about it.
When on caravan with the Airstream club its required to have a CB in truck to communicate within the caravan to make sure everyone is safe especially in the remote areas where cell service is limited or not at all.
I will keep my CB in my truck and on during travels trying to keep up with traffice and other thing going on down the road.
