The newest field at Gladiator park. Von zipper’s 80 walls are made with over 350 t-posts and 9,500 feet of 4″ PVC pipe! You won’t find another zipper field made of PVC anywhere in the world! Make your way thru the zipper down the center of the field. This is a very strategic field. There’s a lot of places to hide and an equal number of places to get shot from.
