Having survived much of the June season, I have two more "peeps" for you (if you can stand any more):
1) The Mapquest Specialist: This is the guy who decides that the shortest distance between any two points in the hall is - right across the bandstand! (Why is there never a cattle prod when you need one...)
2) The Lulav Shaker: This guy feels a religious obligation to grasp your speaker pole with both hands & shake vigorously. Extra points if he can actually topple your speaker and injure someone.
