My two cents:
I love the idea. We did something similar a couple of years ago with Phil Jensen, Bill Judge and maybe six others and I would want to do it again. Not sure I need one more tee shirt to wear only once. It's a little like herding cats. Lots of side conversations and hard to keep everyone focused on a central conversation theme, especially as the crowd gets beyond a half dozen or so. About the only day for me would be Tuesday as Doug's auctions are on Monday and Wednesday begins set up. As an aside, I tried to get a reservation for a tour of the Neon boneyard for Tuesday 6/18 but was unable, maybe because it's too far in advance. I wonder if there would be interest in a CCGTCC-only tour on Tuesday.
