NOTE: This requires moon gravity.
From where you start, turn right past the tour bus and where you did/do the Parkour tricks. After passing the Parkour tricks area you will see a QP on the left. Spine transfer it and land on a roof pointing to the orange building. Jump off the ramp and land on the orange building. Don't go to the left or you will be placed back somewhere else. Get off your board and walk along the right side of the building. Down you should see the place where you steal/stole the naked lady statue. You will come to a corner. Turn left and jump into the hedge of further. You will land in a parking lot. From there go outside and hopefully you will be in Santa Monica
