Stall on a car that is moving and skitch it through town. Jump off when you are about to fall. You will get a lot of Stokens.
Start at the entrance where the cars first enter. When the cars come through, hold Up until you are skitching. Ride on that car until it goes around the city and starts to get near the entrance again. Jump off before you get to close to the entrance. Do not go through the entrance or you will not get the Stokens.
