Tony Hawk's American Wasteland Easter Egg - Sign in Doggtown

The first thing you have to do is go to Santa Monica. Then, where you help Joey B. get the stair set, there is an L-shaped building behind you. After facing the building, turn the camera to the right and up. There is a sign that says "Skillz Inn," a reference to Aaron "Skillz" Skillman, one of the games producers.
