I live in Wabash, IN. I'd love to take some classes so I could do my own calibrations but with the money involved + travel and where I live I doubt I could make any money at doing other peoples sets around here. Gregg Lowen is the one who got me interested in isf stuff and I was going to take one of his classes, (he's doing THX certification along with isf stuff)...but with these difficult times, I doubt that it's in the cards any time soon.
