Yeah, I had a hard time getting a feel for the place too. Their website is kinda not well suited for retail games--I think by design. It's not clear what $100 gets you, I think it's just one of the zones. It's why I brought it up, to see if any one had had any success there.
I think the best course is just to go out there and talk to the guy. It appears to be staffed during regular business hours, and I think they'll give you more run down.
I agree that it might not be ideal--esp wrt to cover. If you're in this thread, you know what the foliage cover is like in central oregon, not very nice. But there appears to be a new-ish building scenario that is maybe a dozen acres of building and roads, so it might be well suited for a fallujah type scenario rather than the hide and crawls that are more popular on the wet side of the mountains.
If anyone gets an organized game up, make sure to post in the calendar. I think we might get some interest from folks all around this part of the state.
