No alchohol on Main grounds proper, but overlooked in campgrounds as long as you are not flaunting it.No dogs or durgs, period.

Took Kate (14 last year). She listens to stuff like Marilyn Manson, Korn, etc, and she had a BALL!! The midway is almost like the county fairs/carnivals you remeber from childhood........been trying to think what this festival is missing, and just can't. All the big guns are here, and all act like real people, had lunch with John McCutcheon and Frankie Gavin once.......
