I don't have any regrets about missing bands. I didn't go to the first ProgPower show in Chicago in Feb 2001. People continue to wax poetic about how great Pain Of Salvation was at that show, but seeing as how I was never a huge fan of them to begin with, I am not too broken up about missing it, heh. Subsequently, I went to ProgPower II in Nov 2001, and have gone every year since, and only some kind of dire emergency could keep me from going in the future. I have been familiar with at least half the bands every year, some years with almost all of them. So even if there are bands I am not that familiar with, I don't skip any performances. I don't drink that much, so I've never had inebriation / hangover issues that made me miss bands, and I make sure I have enough to eat (but not too much) before the show, so I don't have to run out in the middle for dinner. Now, I know I'm not getting any younger, but so far I've had enough stamina to get through all the bands over all 3 (and now 4) days. And I mean standing up. I don't sit for performances. I tried that a few times in years past, and paradoxically, it left me with even less energy than if I were standing.
