I'll bet they are laminated onto a table top somewhere. Or they are being used as wallpaper. Or they made hats out of them and use them at the PoC ride.
Steve???.....are you there Steve??? Aarrrgghhh! I think Steve has been beamed up into several parallel universes!!! Don't worry, we'll get on Mission: Space and see if we can retrieve you!
Mike....that's quite a stumper, and I'll guess that the original menus were sent to the ESPN Hall of Fame or some other noteworthy museum!
And I'll toss out a numbers question to accompany that tough question:
How many people does each vehicle hold in the Universe of Energy?
Carpe....yes, I guess that's true for many of the rides at WDW. But I'm going with the quoted "standard" number. Maybe the portly folks get offset by the wee ones!
250 is too high. That would have been close to my guess too...I was surprised at the number I found. By the way, I'll accept any answer within 10 people of the number I found.
