My Old Man, was in the Air Force as an M.P. in country for two years 69-71. I don't know exactly why, but as an M.P. he had to go through Survival Training School in the Pacific NW. Same as the pilots. In HIS briefing before the dreaded two weeks in the woods with only 2 days of food and whatever would be in is survival kit, he was briefed on what animals that inhabited the area. One of which was what he later recalled was a" large bi-pedal humanoid, that goes out of its way NOT to be detected, known to the locals as Sasquatch". He told me that this very basic sketch of the creature was in his opinion to be "a mind game" to seed another thing to be scared of besides being captured, starving to death or of exposure. So, he just ignored it. Remember this was '68, no one had really heard of Bigfoot. It wasn't until the 70's and watching In Search Of that he remembered that briefing. And till this day the old ******* still refuses to even speculate the idea that they exist. Jeez.
