I have actually stopped and saw these a week or so ago. The guy does this as a hobby and wasn't just hoping to win the prize, but also get some attention and possibly find a position in a job that would do some similar work. From what he said when I stopped and talked to him, he had working lights(eyes and headlights), and was going to use sound bytes from the two movies so they would seem to talk to each other. I haven't been able to go up at night and see them then, but these are truly amazing, even though they are not full scale. By the way, he had the Bumblebee up last year, and decided to add Optimus for this year. He actually set them up in his back yard a few months ago to test the balanceing and to make sure they did not fall over, the day I saw them was pretty windy, and he seemd to do his homework because they are very stable.
; I've gotta respect someone THAT dedicated to holiday decorating, even if it isn't particularly Halloween related. I'd have done a Jack Skellington or something m'self, if I wasn't too lazy to make stuff like that.
