Hot damn this is a kick-ass piece of video -- the Mansion with the lights on, it's like a cross between seeing your parents having sex and catching the hand of God rearranging the laws of physics while your back is turned.
On 08/13/06 we were riding Haunted Mansion at Disneyland when the lights suddenly came on. We later learned that it was because a few kids tried to steal a prop. They were escorted outside by CM's and dealt with by security.Link (Thanks, Ricky!)
Update: Andrew sez, "I instantly thought of the video I had recorded of Space Mountain with its lights on, which I recorded on my trip to Disney World last week."
Update 2: This video has been flagged as private, so you and I can't watch it anymore. Man, that sucks.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
