And while we are on the subject of shuttle loops, here is one I hope sees the light of day again and doesn't just rot away in some field.
AstroWorld's Greezed Lightnin is now awaiting construction at Joyland park in Texas, but it has sat in their field for several seasons now, I am starting to lose hope
FYI - This photo must have been from opening season. The "Greezed Lightnin" logo has not been added to the saloon and the stripe on the train is white. It was later repainted dark blue.
