Accoss the street from the Spectrum in Philly in the park 88,89. Yum Yum Man, Daily Dosses, The Family Tee-Pee and drum circle........Camping and vending along the asphalt path (both side) gave it a carnival midway feel.
RFK (insane) ....... $25.00 bucks for multi night runs. Funk Bus,fatty french bread, killer stir fry guy,drum circle under bridge for three days straight, tunnel before and after show, two for one and one for five, vegetarian lasangna people, national guard showers, ice delivery, etc etc etc etc all make this place above the rest. Many more great places, however never quite as centralized or organized for 3-4 days. Midwest/East Coast Honorable Mention : Albany,Deercreek,World amp in 90, Rich, U-Conn, Buckeye Lake.
