All the fields at R.P.G. are what I would call concept fields.
You have two fields (Area 55 and The Zipper) made from 55 gal. plastic drums (The zipper is kinda like the ladder field at badlands). Then there is one field (Thunderball) made out of plastic tarps. There is the field in the woods( the Woods) made up of both spools and 55 gal. plastic drums. The last field is made of both tarps and spools. I am told by most people that play them that there fun and interesting to play.
