Here's a bigfoot one for ya...
Getting close to twenty years ago now a real good friend of mine and I went scouting for elk in western Montana. It was an area we had scouted and hunted before and has a pretty solid grizzly population. It was early August and we were both packing our hunting rifles. Both of us were fairly poor and had great rifle optics and crap binoculars, neither of us owned a pistol at the time and we didn't feel like being Tim Treadwells predecessor in the bear sheet department. We had hiked up the trail in the dark planned to seperate for the morning to do some scouting.
We got to our predetermined split point 1/2 hour before sunup and I headed up one ridge and he headed up another ridge. Both of us had about an hour long hike to get to the top of our prospective ridges, each of our glassing spots would allow us to see back down the trail and into different bowl to glass and watch for elk as they headed to bed after the sun arose. About 1 hour after daylight I happened to look over towards his ridge and I could see him heading down the ridge and away from his overlook. He was moving pretty damn steady but not running. I actually turned up the power on my scope to see if I could see blood or anything on him, or some kind of reason for his heading down the ridge. He was on a pretty straight line getting out of there, hit the trail and headed for the truck. I figured something was wrong, so I grabbed my junk and headed for the truck as well. He was sitting in the front seat with the engine running when I got there. This is what he told me.
He had been heading up his ridge and was probably halfway up the ridge and the sky was just light enough to see when he spotted a large grizzly on a different hillside than the one he was heading up. He still probably had a half hour climb and the bear was close to a 1000 yards so he didn't really think to much of it. As it got lighter he could tell that the bear was in a large patch of huckleberries and did not seem to be in any hurry to move off. He got to his top of the ridge and the bear was still there, probably 400 yards out now, he said it didn't seem to have moved from the initial spot it was at, and he realized that the bear was on it's hind legs, he wasn't sure if it winded him or not, but the bear just kind of stayed right in the middle of the berry patch.
He took off his pack and layed it down, got in behind his gun and started scanning the bowl below him for elk. He had spotted a few cows with a spike, and a couple of good mulies. He was concentrating pretty hard on the mulies as he wanted to see where they would bed as we would be hunting that area in about 2 weeks with bows. he glanced over his shoulder and confirmed the bear was still in the same spot and went back to watching the mule deer bucks.
He watched them bed and then tried to find the elk again, which he could not find. When he glanced over his shoulder and saw the bear. Same exact spot. he realized that the bear had been there for a long time now, and always appeared to be standing upright. He'd seen plenty of grizzlies before, but never seen one stand on it's hind legs for close to an hour. He decided to take a closer look through his scope. He said it was a big bear, very dark furred and just standing there eating berries.
He said he watched it for probably five minutes, knowing something was wrong, then realizing he was looking at the face of a man. Said when he realized he was looking at Bigfoot he felt nothing but fear. Pure fear, nothing else. Almost as if it was standing right next to him kind of fear. He said he could not get off that ridge fast enough or out of its sight. He came off the ridge towards my side at a run dragging his daypack then slowed down just before I must have saw him cuz he was scared he was making too much noise and it might hear him. The "creature" was not on my side of the woods and he could not bring himself to turn up the trail to come get me. he said all he could think about was getting back to the truck.
Now before anyone calls bullsheet on this story, let me tell you this. This feller had killed five good bulls in five years out of that trailhead, and as long as I hunted with him he would never go back up that drainage. I've been with him when we've been bluff charged by griz trying to pack out elk. After sitting in the truck and watching his hands shake when he reached for the column shifter, I believe he is damn sure he saw a bigfoot. Hell, I couldn't get myself to head up that trail for five years after that, and I had killed three bulls there.
We had about a 90 minute drive home, and most of it was in silence. About 45 minutes into the drive, I asked him why he didn't shoot the damn thing. He said it never crossed his mind. I've only been back in there about 3 times since that little scouting trip, and you better believe me I kept my eyes open for a grizzly standing on it's hind legs.
Do I believe in Bigfoot, hell I don't know. But I know one thing for danged sure, one of the best woodsman I ever knew damn sure knows theres a bigfoot.
