My cousin tried the panzarotti at Rehoboth Beach a few years back...turned into a miserable failure - closed after one season. The original panzarotti place is in NJ (Medford, I believe), but they always bring the truck down for the I-Fest!
I haven't been to the I-Fest in about 10 years now. The last time I went I saw two teenage girls get into a fist fight at the seafood cafe...no high-pitched squealing and hairpulling, this was out-n-out fist meet face. Both of 'em landed 3 or 4 good shots, got some blood flowing out da nose, then they ran through the crowd. That was enough for me.
The cover should help with the punks. I think they should close the midway and focus more on the culture, the food, and the music (and the wine!).
