I think Spring Break is just a weird time to do it. It looks good on paper because a lot of younger fans a freed up, the entire week could be made into a vacation by some, etc. However, I don't know if appealing to the school/vacationing crowd is worth the increased travel and hotel prices (raising the festival's costs). On top of that, spring break was actually the only thing that stopped me from attending last year. Since my family was suddenly freed of the obligations of school, I was pulled into a family vacation. That scenario could affect the oldest potential attendee.
I don't know, maybe was worth it last year. However, I just don't see the fanbase of this genre as young enough to warrant the spring break timing. I mean, I've been going to ProgPower since I was 15, and my friends and I felt very, very young for several years.
I'm clueless on location though. I'm stuck here in Northwest Arkansas with nary a metal venue in sight.
