So, I attempted to get tickets on 2/22, got here there at 7:30 AM, and I was probably 20-odd people in line, which was discouraging to say the least, but I decided to give it a shot, yep, didn't workout.
I tried a week later, 3/1, showed up at 5:00 AM, to be on the safer side of things. I'd have to say rushing for this show is a crapshoot. But it's now nearly 8 AM, and there are only 3 people in line. Last week at this time there were nearly 10 times that. So, in hindsight, I'd say a legitimate timeframe to show up is between 6:30-7:00 AM.
