Head north and go to the Wrigleyville area and find Wrigley Field. Go to the northwest end of the ballpark. Park your car, get out. Walk over to where it says "Tickets" and press Triangle. A secret area located in the southeast corner of the ballpark will open. Return to your car, drive around to the southeast corner, and drive through the now opened gate and into the ballpark. Drive over to the ramp, get out of your car, walk up the ramp, turn right, and follow the walkway to the secret car.
