Hershey Park is the complete opposite of the "Worst Park In The World". Storm Runner is by far the best intamin rocket coaster, and Lightning Racers is a great coaster that ACTUALLY runs both sides all the time and really races. Wildcat from what I hear is 100x's better and smooth. 3 GCI Wooden Coaster, 1 Classic Wooden Coaster, Classic Unique B&M Invert, Very, very unique rocket, and the another classic, looper. How can you go wrong with 3 GCI's?!!?!
ANYWAYS!! Back on topic...
The worst THEME park I have been to is Geauga Lake. The park thrill-wise is top notch, but theme wise the park is down on the bottom of my list. Very generic, and plain. Then again it was owned by Six Flags before Cedar Fair got it..
