There always had to be a couple gnarly tricks in the Intro, but a few I feel have been forgotten
New Blood - Chris Cole bs flip the Wilshire 15. Didn't like the angle, probably why it was in the intro.
Ride the Sky - Billy Marks 360 flip bs boardslide. I had heard about him doing this trick at best trick contests, and it was a shame, to me, how this trick was relegated to the intro.
Yeah Right! - Eric Koston nollie back heel a bump to bar. Might not be the craziest bump to bar, but jesus what a thing to do at such a spot, and in 2003.
Anybody got any others?
