I just came across this post on JimHillMedia.com. Apparently active annual passholders have a chance to win a sign from Space Mountain! Not just any old sign, a sign that has been there since the opening. There is a picture of a space mountain sign in the post, but no word on if its THE sign.
I'm really curious just which sign it is, mainly so I can find out how big it is and if it will fit anywhere in/around my house.
The sweepstakes is running from March 1st - April 3rd so get moving! For those of us that can't make it to the parks in person, you can also mail in entries somehow (I'm trying tohunt down that information now).
Good luck!
