Report 2657: A tree stump moves closer to a group of young boys

Unfortunately, my sighting is not recent at all. It happened in the late 70's in a town called Flagler Beach on the east coast of Florida. At that time the area was still very rural and undeveloped. Myself and a group of other kids, I think a total of 8,were down a deseted open flat, a small peninsula,primarily used for nesting birds. This is late morning under a clear sky in August I should add.  We were near one of the banks when I "felt" something. I look across the water to a hill (approx 200 yds away) covered with course brown grass with a tree stump at the top. Seeing nothing else I went on with whatever we were doing but it occured to me that the "tree stump" was very much out of place on that hill. I look again and "it" has moved downhill closer to us. Realizing it was much taller and moving I pointed it out to the others, turned to see if they looked, when suddenly everyone bolted. Since the older brothers ran I too took off. About a mile later I finally asked why they ran and they said it moved it's head. To this day I still regret leaving. What description I can give is this: "it" was tall, 7 ft maybe. It appeared to covered in long brownish/grey fur and it did indeed stand upright. I call it a bigfoot because I am certain of what it WASN'T. Definitely not a bear and the liklihood of it being a human in a costume is extremely remote. My arguement there is one, Fla in August can be brutal even to the locals, damn near suicide to put on a heavy costume out in the sun. Two, the location. With the exception of the hill all else around was marshland, not very easy to get to. I know because I tried to at another time. Also as I stated it was very remote so the liklihood of a hoax at that time and place just doesn't add up. I cannot give more details of the bigfoot but I can say for myself that I didn't perceive any danger from it. More of a curiosity. As I stated I ran because the older brothers' did, it was their fear that had me running and to my regret that they did. But I will never forget that day, even now I still can see it all very clearly.
