I have a field behind my house and I want to do something with it.?

What I want to do is clean it up, and put an airsoft place in it. like put cover and a couple small buildings with windows and stuff. I live in a small town and I wouldnt make people pay to play. It would all be free, just bring your gear. there isnt much to do in this town, there are no malls. the only thing to really do is bowl and drink and do drugs. and we all know that bowling isnt good for everyone, and drugs are bad mkay. there are houses around the field, but im thinking if i got permission from people around the field, and asked to local police I might be able to do it. like i said this is a small town and I doubt anyone would really care either way. the field is just going to waste anyways.
