I've only ever seen one bear in the wild, it was a black bear up in Yellowstone several years ago. I was in a car, and I wasn't sticking around any longer than I needed to snap a quick picture.

I saw a video a few years back of a couple of guys that were up in a tree stand in the woods, when a black bear juvenile came bursting through the woods (being chased by a larger male), and I was amazed at how fast he was running, and even more amazed at how fast he climbed the tree the two men were perched in.

It was like watching a 150pd squirrel go up a tree with just about the same grace and agility you would see from one.

They are incredible creatures. This guy got very lucky, and glad he came out of it unscathed and with a great story to tell.
