I was there: front row.
When we pulled into the parking lot after a 3 1/2 drive (plus a quick stop for food), we saw a line going down the length of this building (which is long -- a long rectangular building used for conventions and some entertainment show -- alas, I wasn't able to go back a week later for Atlanta Midget Wrestling, haha) and out into the parking lot. Many of them out in the light rain because the covered awning couldn't hold them all.
As we approached, they said people who already had tickets could go in the left door (no real line) so all the others were waiting to buy tickets. Huge walk-up. Later saw it announced as 1,200, which seemed about right.
I don't quite know how to compare a "indy" house show experience to being at WM30, but apart from that WM this was the best show I've ever seen live. Everything worked. Every match was anywhere from solid to great. Crowd was really into it.
They announced before the intermission that they're coming back in August, and sold tix during intermission ... so I scored front row for that show too!!!
