Why George decided he would rather haunt his workplace for the rest of eternity rather than chilling at his home or with his family, is already enough of a mystery to me. The teenagers who took the above photo (which i stole from the examiner.com) claim that you can see George emerging from the mist. I don't actually see a face, or a hand or even a human-looking silhouette in there, but maybe i'm missing something as the photo has risen to online conspiracy theory fame.
Park guests who are savvy to this will often do the same and some people think there might actually be clues for when George will come out to play.
In the Auction scene-you know, when they're all yelling "we want the women" (or redhead, no one is sure)there is a tower. If the light is on in the tower, you can expect a slight ride malfunction. The same is true of the prison scene with the dog- if one of the doors is slightly open, beware of George's wrath.
He also doesn't like to be made fun of, so if you really want to see him, by all means, mock the hell out of him. See what happens and let me know.
