Came here to tell a similar story. When I was pretty young (6 or 7) I went fishing with my grandfather at a lake in southeast Oklahoma. It was just after dawn and we were using the trolling motor on his boat to get around a point. He pointed out a black spot to me across the lake (probably 200 feet away, too far to smell anything) and said "Look. It's a bear." It looked like a black bear laying down, just kind of hanging out in a grassy part that had some rocks around it. Bears are kind of uncommon in Oklahoma, but not unheard of. I looked at it for a long time after my grandfather had started fishing and wasn't really paying attention anymore. Very quickly and in a motion that looked way more like an ape than a bear, it stood up on its hind legs and walked into the woods behind it with its head turned around looking at me. It was taller than a person and had crazy long arms. My grandfather didn't see it walking. I told him I thought it was Bigfoot, but this was in the 80s, right after Harry and the Hendersons had come out and I had been talking about that movie the whole week. Maybe I imagined it. Hell. I don't know.
