I am a veteran of all the coasters at Six Flags in St. Louis. If you want to know anything about any of the rides there, I can help you out. However, I have never been to Six Flags Great America in Illinois. Thanks to a new video share, we can all see what it's like to ride the coasters there (and non-coasters, too).
As I have pointed out previously in this space, I have a problem with heights. Always have had, always will, I'm afraid. I don't have a problem with speed, or twists and turns, but if we're going to go higher than about 10 feet, you'll have to count me out...
