It's a funny thing to see in person. I only saw it at night but it was outlined in Christmas lights.
Cool place to see and take photos. They converted the garage into a cute gift shop while preserving the use of the original garage doors which are massive. Haven't done the tour though, but I bet it would be cool.
Visited this place Jan. 2013 is it's awesome sight to see up close! Luckily, someone left extra spray cans behind so I left my mark.
