I've been to 8/16, 11/28, 12/27, 2/14 and 3/13.
The workers for the most part are very approachable for autographs/pictures unless they are running late. The atmosphere at a show is awesome. Here in the northeast, you'll see the same 1-200 fans at every show and you start to know them all. The 4/23 card on paper seems to be real good and I hope you enjoy it. Tell all of your friends about it..the higher attendance, the better chances for more returns (even though there is already a return date in July for St Paul)
