Here's a little bit of trivia for y'all. Back when Arrow's XLR-8 was being designed for AstroWorld, stand-up coasters were just starting to be introduced. Well some big-wig in the Six Flags organization though that is would be a good idea if that ride could be converted into a stand-up ride, so there was enough clearance to the supports, ground and anything else to clear the additional length to fit a standing passenger coach. This was also the early days of Six Flags' ride rotation policy, so all the footings for the supports were set at a common elevation to facilitate a move to another "flat" site. Being a young guy at the time, I questioned both decisions since (1) to me part of the fun of the suspended ride is swinging close to stationary objects, which were placed farther away for the stand-up clearance and (2) I remember that there was a boat ride or something under XLR-8 and we spent a lot of effort to avoid that and I figured that there probably was not another site like that anywhere. Anyway, when I heard that AstroWorld was closing, I thought about how "easy" it would be to move that ride somewhere and make it a stand-up, but unfortunately neither thing happened.
