Here's another video of a 'ghost', riding along with a Disneyland Maintenance Worker as the ride is tested. The video is from Disneyland's own cameras that videotape each ride (to look out for hooligans!).
Just click image above.
I find this video humorous - watch what the maintenance worker doesn't do! I mean HE WORKS THERE! None of his co-workers warned him?! Maybe they didn't tell him just for the reason you'll see on the video! At least I laughed!
Anyway - you be the judge - ghost or no ghost!
(as well as laugh out loud or just a giggle!)
