Darn... we already went. NASA Physics Day was May 19 and several representatives from our team (myself included! I didn't go last year...

) went up with our robot. We got a corner in a building with a NASA quiz game and got to talk to people and let them drive the 'bot if they wanted.
P.S. Top Thrill is good, but Millenium is better because it's longer. Just as a hint for the interested.
