Grind Straight Up A Wall
From Glitches
From the game Tony Hawk Pro Skater 2X for the Microsoft XBOX
Find a wall that lines up with another wall in a 90 degree angle. Get some distance from the corner and skate along one of the walls leading to the corner. Almost before you hit the wall ahead of you, ollie (jump) and wall ride along the wall you were skating against. If done correctly, you will wall ride straight up the wall in front of you.
