You would need a 5 ton wrecker, a full set of rear tires, and be able to get in and out in 10 minutes or less. This area is only 75 feet off the road through part of the Reservation. Heavily patrolled by AF Security Police. I was technically breaking the law walking around taking pics, but I have been doing things like that for years and years.
There is an old M37, a M38, a Deuce tractor, an M151, and all manner of late '50's and early '60's civvy vehicles stuffed in those woods. When I was a kid, I drove all over those woods in my Jeep truck. There are M135's, M211's, WW2 halftracks, AA guns, 40mm quad Bofors guns, aircraft, tanks, and God knows what else in those trees. If you ever saw the movie "The Green Berets", it was filmed in a section called "Little Viet Nam". The Son Tay prison camp rescue mission was practiced out there, matter of fact, they built a replica of the camp for that mission.
The area was just about abandoned in the late '70's. Then, in the early Eighties, Project Underbrush was established out there. I believe it was counterinsurgency and recce training. Large areas of the reservation that had been accessible for years to hunters and kids were suddenly off limits. A series of advanced sensors were placed in the woods, as several of my friends found out when trying to sneak in and deer hunt. A couple were arrested and interrogated before being released and told to "never try that sh** again, boy!"
