BackSide BoardSlide

1) Approach the thing that you're going to slide at a straight angle about half a foot away from it at a good speed that you feel comforble at.
2) When you come up next to it do a 90* ollie on to the thing you're going to slide.
3) When you land on the thing you're going to slide put your weight on to your heels. (If you are sliding the way you're facing.)
4) If you did that right the board will slide. Now to get off this depends on what you are sliding on. If its one of those bike racks that you turn upside down or anything that just stops with nothing in the way of your wheals then all you do is turn your body (and feet) the way you want to get off. But if it does corner or there are things in the way of your wheals then you are going to have to go up on a 30* angleto clear it.
This can be a cool looking move. When you get good at it you can slide things quite long. To do this you need more speed.
