This is a bit offtopic for my blog, but I found this video browsing around Youtube today:
And you thought skydiving was scary! This has to be one of the most spectacularly terrifying things I've ever seen anyone do, and this is coming from a guy who likes to get close to tornadoes.
You can read more about wingsuits -- the kind of garb this guy was using to "fly" over the mountain -- over at Wikipedia. Yikes.
