It was actually a piece of privatley owned property near the ventana canyon area. I think its the part of the sabino canyon river that runs down into tucson. The downside was, that there were too many buildings in the vacinity (Its almost in the middle of a community) so to say the least someone eventually complained. So even though the owner gave us the permission to play there, the community was against it, and we could never play there again. At least we got to play there for around four months before someone complained.
Ive always been looking for another similar area, with running water, and lush riparian vegitation. I occasionally grow tired of the same desert scene, and would kind of like a "jungle" to play in again.
Theres really nothing else like it. It is so much different than an open desert battle. There is a different kind of mood, and a different kind of fear. Because with all of the dense, green vegitation you are emersed in, you have no idea of knowing if the enemy is lurking in the distance, or right on top of you. The vines and leaves hide you and your enemies as well. You learn to tread quietly, and not to brush branches loudly. And at any moment, enemy fire can seem to come out of nowhere, and start clipping off pieces of your surrounding vegitation.
