I have a top of the COBRA line tuned to chan 19, a vintage Realistic (Radio Shack) on 13, a hand held Midland on ... OFF, and have never used any of them for emergency.
I grab the 100' wire and find a place for the other end of it and use the Kenwood TS-2000 ham rid.. Way better communications.
That said the CB's do serve a purpose as they have been known to alert me to problems before they become major issues. That vintage Realistic, back when it was not so vintage, alerted me to a road that was blocked by an overturned seim, It was too late to take an alt-route but thanks to the info I slowed,, big time... When I got to the 4 car accident that happened at the back of the back up.... I was not part of it.
So having a nice BIG maxi van (Capacity 12, 13 if someone sits on Somtow's lap) (long story) (That is S.P. Somtow, you can google him) (That young lady was VERY happy).
Back to story: I sheltered the players in the crash thill the police arrived to do the report, sheltered the deputy, and took them home.
