Oh they have them. They just don't use them. I always remember laughing my butt off when they were doing work on I-40 through Arkansas..us old hands had our CB's on and working, talking to get the word out about the accidents and slowdowns and the mile markers there were at...so we'd get off at the recommended exit and run US 70. As we're running along, we'd hear: "Hey what's going on up ahead? I had my radio off so I didn't have to listen to those old guys chattering." LOL Happens everytime. The one's stuck, didn't have their 'ears' on...and it was a pleasure to 'school' them why they should have them on and listening...but...youth demands to learn the hard way...so us old folks can get some laughs out of their eagerness.
