I've seen a few of those urban downhill vids before, but man that one felt extra-dangerous. So tight down some of those stair sets towards the end of the vid.
The physical quickness always impresses, but it's the vision that impresses me most. You can see he's spotting tiny details and choosing lines several corners ahead. I know to look up and ahead down the track, but rarely make it much past the exit of the next corner or "chicane" around trees or rocks or whatever - but watching him is another level. Actually - make that several other levels! Haha.Such a joy watching Sam ride.
