bump. it sounds great. some of my friends are into that airsoft business. personally i haven't the time or money. but as far as i know, no vehicles are allowed so where do you go? they would be interested i am sure. incidentally. my mate found a great way of producing grenades that he called "bangers and mash". you take the bangers from farmers crow scarers and some big old spuds. drill a hole in the spud the same diameter as the banger. wrap the banger in foil and insert into the hole. when you lob it, it is supposed to go a long way and when it goes off; everyone in the area gets a liberal coating of mashed spud.
