Was browsing the boards of MouseTimes and just happen to run into this thread about San Diego's CBS 8's five part series on what happens at Disneyland after the park closes. Doesn't totally answer your questions but is definitely worth a looky-look. Here are the links to all of the five parts:
Indiana Jones Adventure
Pirates of the Caribbean
Tower of Terror
Horses of Main Street
Cleaning the Park
So I've been wondering what you have been meaning when you say "ghost ride" in your captions because here in the Bay Area, it means to get out of your car while it's still moving and dance. Being that I see no car, I was wondering if the term means something different somewhere else...
