Mounted mine on my Yakima roof rack, just like Mark did, except mines on the driver's side. And, yes, that is a Pink CB antenna!
Had my handheld CB/mic combo mounted on the LEFT side of steering wheel, where the rheostat was.

Hmm, why is it that 2 of us have a certain young lady hanging on our CB antenna???.....Oh, you were away for a while...have you been introduced to Jo's ORW?
