Kiley is the guy to talk to for that. Get all your info together, such as exact location you'd want to be playing, find out whether it's national forest for sure and then go from there.

It can be done, and we have the network to do it, but we will need some exact maps and coordinates of the area to be used. Photos would also be helpful to convince the persons doing the footwork (aka 'me') that the venue is worthy of the effort and sustainable for a reasonable amount of time.
