Very cool.. as famous as this guy is, and he's
still posting up backyard videos. Tony Hawk's
self-filmed backyard impromptu session.

Baselining
The new 'Extreme' sport.. looks pretty friggin extreme to me. A combination of slacklining and BASE jumping. I'll stick to tamer stuff like rockclimbing, mtnbiking, skiing, and 'extreme' engineering thank you! :-)
