I think the guy from Columbus is Jim, may be a Barn fan.
I used to listen to him back when he had his night time show in the early 90s but switched to the other station's show because I thought he was too much of a jerk back then. And this was when he had normal people calling in.
As for how a show like his got on Sirius, have you ever seen Honey Boo Boo? I enjoyed hearing people from outside the area call in, but I like a show with a local focus. Sadly, most of the locals are the idiots who ramble and never make a point.
Do the regulars have a special number to call so they always get in every day?
