One of my Grand-dad’s rules was that, whoever last used the tool shed (which was away from the main house), had to lock it up at night. One night, my Dad happened to to to the tool shed before sunset to lock it up. He said he reached through the chain hole to grasp the other end of the chain, to secure both sides with an old fashioned padlock. Something inside grabbed his hand. He was able to struggle away from the grip on his forearm, and he began to yell and scream.
As he ran up the path toward the house, my Grand-Dad and Uncle were already on the way down the path toward him carrying flintlock guns. (I have seen those guns.) My Dad was apparently pretty frightened by the incident. Now, there are tribal superstition and culture-generated aspects that my Dad applied to the story. If you remove those cultural aspects, you are left with a typical, currently-reported bigfoot encounter.
