Unless you live under a rock in a cave in the jungle, you should know what an indy looks like. Be able to ollie kinda high. At least over a board on it's side. Ollie and as soon as you get the back wheels off the ground reach your back hand down toward the middle of the board. Suck your knees up so that the board gets closer. When you are close enough, grab the board and hold it for a split second (hold longer for a badass Indy). When you get ready to land just let go and get back in the landing position for an ollie. Get good at these and try them off ledges and shit.
