I think the guys name is Bob, but i could be wrong. Bob said that the price for spaces were to be according to size and the guy (DEC guy) was not doing that, no ryme or reason to the prices. It sounded to me like DEC only let the ones holding the event use the land because it was being used for that before DEC moved in.
So maybe the guy who was setting the prices for spots started doing it a few years ago, that is when the attendence started going down.
