A friend once went thru a survival school at Altus AFB, OK, which was next door to some Army facility. In the E&E portion of the class, right after a few days of being "prisoners," they were told to take off. In a short time they would be chased by locals who were acting as the badguys. If they managed to stay free for 24 hours the class was over, if captured they got two more days of prison. Then they were told not to go beyond such and such ridgeline, such and such fenceline, etc. My buddy, a former Eagle Scout, figured that was BS, so he beatfeet to the fence, hopped it, and spent the next 24 hours enjoying some well stocked Army outpost. Then hopped the fence again and went home...
