Thanks for the link. It sure wasn't what I expected. Sounds like one of those alleged recordings of bigfoot.
At first, it didn't scare me. But then, it made the movie "Deliverance" come to mind. I actually heard the banjos starting up in the background. At that point, it began to scare me.
Oops, forgot to italicize the first line, quoting you. Anyway, listen to the yell again, but put this in the background:
Hope this works...
NOW it is scary, no?
