Umm... Have you checked the RSVP section? There's Fightertown on the Westside, other than that, you're out of luck. My question, though, is this: were you just looking for any old place to play? Like just a field or something? The reason I ask is that most of the land in close to the areas you're talking about is private or way out in the desert. The bit about the "building" also bugs me. Do you mean just abandoned buildings?
