I remember decades ago I had a friend was was an exec at WB. I got a pass from him and was dropped off by him in the middle of River City, lowa and told I could go anywhere there wasn't red lights or signs. I got not only a free run of the stdio, but also Burbank Ranch. I wasn't allowed to take any pics which was a shame, but I'll always remember the odd sights - like the Waltons house across from the Fantasy Island house at the Ranch. Or the western town with all the doors missing (apparently they had taken them to a standing real set for Maverick, to make sure it matched backlot footage).
