Saturn V are just too tall to deal with high winds and standing upright. The tallest
standing Rocket is the Saturn I in Huntsville at the Marshall center. I haven't been
to Houston but photos of the park show none to my knowlege taller. You get to see that lovely Saturn V in Houston and Huntsville due to the cancellation of their
moon missions Apollo's 18 & 19. The one in Florida is the 500F test article they
used to test facitities at Complex 39 in 1966. They're expensive "lawn ornaments"
not being used but they do make great 1:1 displays!
