I hauled ass to get to Guitar Center by 1:00 (I teach in Flint until noon). I showed up just in time to not be able to see the stage, just the backs of everyone's head.
Luckily, I used to work at that store. The manager pulled me around the way Petrucci came, and I essentially got a VIP spot about 5 ft behind and off to the side of the stage. This is why you don't burn bridges when you quit your job.
Of course I stuck around and got his autograph. The guy right in front of me asked "what do you wish fans would ask you more about?". So I said, whatever the answer was, that's what I was going to ask. Cool dude. Killer arms.
