Check your local area for hunting clubs. They need places to shoot, too and they know all the farmers.
Get some buddies together and pay a landowner for the use and keep it nice and clean. Don't shoot the animals.
Lots of empty farm land sitting around empty these days as well - that an owner wouldn't mind making a few bucks a month from for nothing.
Use your imagination and ask around. Ads in small local papers. Well worth the effort.
