Shaun White Skateboarding

The easiest map by far is the Restricted Area Map. Just grind up and down the train tracks that have ramps at the end. Slide up the ramp and back down for speed then zoom down the side of the train track and every so often just keep jumping from side to side. I got about 700 from one pass didnt take long at all.

Picking the right location is key to getting it. Also having bought a couple of vert and grab tricks in your trick book helps to keep tricks fresh as to get the most points out of each trick you perform, though this is a very minor minute detail. There are 3 main maps for this.

Rising Island Park

I consider this to have the best location. At the far left of the map there's a square pool with an attached but seperate oblong bowl sticking out into the pool from the side, however it's cemented over at first. To unlock it just get a flow level of 2(or a blue flow level) and skate near it. Once it's unlocked just transfer into it, do your tricks and you've got it. If your having trouble finding it it's near the lighthouse tower.

Skatelab

In this map there's another oblong bowl but it's on top of a building thing that's directly across from the big stereo looking thing and is completely on the other side of the map. They're both connected by the vert system they've got going there. You've got to take some sort of shaping rail pointing towards it to get up there whether it's from the just barely raised platform or the platform held up by 4 columns you get to by transfering over a shaping vert and landing right on top. Once you get there though be careful since it's easy to fly right off and having to take time to get back up there.

Conformity Square Rooftops

This is the same location as the other solution states, the pool on the far left side. I tend not to like this location as much since it's harder to get height and the pool is big enough that it's noticable between tricks.
