Yesterday Six Flags Over Georgia announced that their classic wooden coaster, The Great American Scream Machine, will run backwards as of March 10. It will be a limited run. A national landmark, the coaster previously ran backwards in 1992. Now that I’ve seen the latest video, I must say that this looks totally insane! I’ve ridden an invert backwards – no sweat! – but riding an old woodie backwards is a different story altogether.
