Not too sure why that video is SO exciting and has made the rounds on the internet for months now. Happens all the time and some a whole lot more exciting than that one.

As Even said, black bears can go up a tree in the blink of an eye. Last year I had to bonk one on the head with my bottle of water before it would back off as it was trying to climb into my tree stand. I was trying to take some pictures of him as he came up and was right below the stand, but the darn auto focus on the camera kept focusing on the mesh of the stand platform and the bear was a big blur......... which was unfortunate as they would have been good pictures. Oh well............ it will happen again for sure at some point.
