It is a pretty cool scene to see them all at once though. When are you making the trip out! You'd have a great time no doubt.
I've definitely seen all those bands and if I was gonna get on a plane to see a show that plane better be landing in some place like New Orleans or San Francisco or Berlin or Chicago.
The reason why Insub Fest is especially cool for you is because you have been active on the message board related to the festival for years. Isn't you band on their label too? With all these festivals happening nowadays, I think the only one truly worth traveling for is Riot Fest. They've been getting some big-name reunions and putting together some great lineups. Chicago is also a world class city and is fun to visit with or without a punk show.
The Fest (in Gainesville) is pretty rad because there's just so much happening in a concentrated area, but that's getting a little redundant at this point. So many of the same bands.
The one fest I am kinda interested in seeing is Berea Fest in Ohio. Gotta work that day though.
