Thunderbolt at Kennywood....one of the greatest wooden coasters, but has been know to crack ribs when you put your arms up!! luckily has not happened to me, but i cant ride it anymore b/c of a bad back, go to the chiropractor and dont want to ask for trouble. I stick with 1 ride on the Jack Rabbit per visit (my favorite one by far) and that has to last me from summer to summer!
also remember riding Raging Wolfbobs once at Six Flags when they took over Geauga Lake Park....that was rugged!!
