Sean,
We used to have shirts available but they sold out. I heard someone had picked up and started making shirts again, but I can't seem to find anything about it.
I'll be at the show Saturday morning until about noon - I'll be there with my wife, but we're celebrating her birthday that weekend, so I'm not going to drag her around a car show all day. We're going into Columbus that afternoon for a nice lunch and then down to COSI - a science museum in Columbus for a CSI exhibit.
I too am trying to find out if we're going to have a tent or anything to rendezvous at. I guess I'll just wear my CC.C shirt and hope someone sees me!
Jeff
