While Disney does have some really intense thrill rides like Mission: SPACE or Rock n' Roller Coaster...there are hundreds of attractions all around the world that are head and shoulders above Disney in terms of height, speed, G-Force, etc. What are some of your favorites? Also it might be fun to talk about how some of these roller coasters are designed. The physics behind the coasters themselves. That's something that has always interested me. .... Ah...much simpler. Start out slow... To kick it off -- maybe even @Voxel has been on this...one coaster I've wanted to try is Intimidator 305 This thing looks amazing...comment below with some of your favorite coasters!
