Facing into the garage, walk one step onto the black mat in the doorway. Turn back 180 degrees, on your left you'll see a doorway with a polka dotted carpet that is just barely visible. You're now in a rec room, in front of you will be a TV with a glass desk below it. To the left of that you'll see a wall of three windows, head towards the right most window and once you're standing between the right most window and the middle window, still on the carpet, you're done.
