hmm. sorry to hear you've had bad experiences with JKPs. i've never attended any other JKP other than the yearly Milwaukee event. so i can't comment. however, some of my friends and acquaintances from local Chicago bands often go and p(l)ay Milwaukee every year too, and i like to go see them, as well as the other bigger acts that play. Seems like a lot of folks like to bash the MMF but some damned good (if not great) bigger bananas end up playing there. Last year, for instance: Testament, Arch Enemy, Susperia!
i dunno. i'm still sorry you've had bad luck where you are but personally i just go shows and enjoy. i don't get involved in any of the politics of it.
