When I was about 12 a friend and I saw something in the woods, and this video really reminds me of it.
What we saw actually moved though. My friend saw it first, and pointed it out. seconds after I figured out what he was talking about, it started running making a lot of noise from breaking branches and crushing leaves.
I've been really obsessed with this lately, and this is the closest I've seen. The video is probably just a stump, but... I still really question what I saw back then. I would dismiss it, but my friend seeing it and the noise make it hard for me to ignore.
