What was the worst amusement park or ride you've been on?

When Shock Wave was at Six Flags Great America I went on it and it was so bumpy I felt like I had whiplash. Iron Wolf was similar but not as bad.

One of my favorite rides I've been on Batman, American Eagle, Tower of Terror at Universal Studios Florida.

Its ironic that I have a fear of drops so i cant ride the big ones, but I went on the Guardian of Wonder Mountain and Canada' wonderland, and it was horrible, the beginning was the most exciting with a little hill, but it once I got inside, it had these "enemies" you had to shoot with not very accurate guns, and then at the end a platform drops really quickly and its the end, I found it kinda bla
