First get on a ledge that you can just walk off of where there's a wall near by. the one shown in the pics works great. Now while holding down graffiti the wall and hold triangle then circle. you should spray the wall and be able to walk away. now keep holding triangle and circle and walk off the ledge but don't go to to far. now while still holding triangle and circle get on your board and you should warp bak to the nearest rail where you sprayed the graffiti and grind also if done right the grind balance meter will be stuck on the screen.
