Sweeeeeet! Glad the show rocked so hard for youze! ^_^
As for procured memorabilia, I'd say my prized possession is from Oktotenfest 2006, wehn Bella Morte and Hanzel Und Gretyl came through. Bella Morte being one of my all-time favorite bands, I was up front rockin with them the whole time, and then when they were done, I got one of three setlist sheets, which I got signed by the entire band (since they are such awesome guys and just hung out afterwards). Yeah, that made my night, year, and now it is proudly on my wall. I also got a Hanzel Und Gretyl shotglass, bearing their logo and the Jaegermeister logo. Good stuff.
Then there is also the list of various autographs I have in my collection: Papa Roach, P.O.D. (twice), Killswitch Engage, got a picture with some guys from Graveworm. Yeah, it is always fun to really earn something at a show.
