If you go by where the interstate crosses over the Medicine creek you can walk down to the creek and basically be on post, locals would do that a lot to go fishing in the creek. Theres a lot of abandoned mil shit back there including some abandoned horse drawn artillery caissons and some abandoned and overgrown buildings from the 1800s. If you can go on the main post up by the historic district adjacent to the aforementioned woods, theres an abandoned hospital building (The same hospital where Geronimo died) the inside is basically been unchanged since they closed it in like the 60's. I've gone inside once with some friends it's some real Resident Evil type shit.
Feel free to ask if you have questions, I basically have 100% map exploration of the area.
