The Iron Wolf... The meanest stand-up coaster at Great America, and the only one. Riders stand up as they get to the top of the drop, and then they fall down right into one of the biggest loops at Great America. After a number of twists and turns, riders are thrust into a nasty corkscrew. A couple of more turns await the riders, but no more upside-down loops or corkscrews. I recommend the Iron Wolf to anyone who likes coasters, except of course, to people with back or neck problems...
