^^I rode it every year from opening until 2001. The only noticable difference (other than the fact that it got rougher due to lack of maintenance) was a slight kink in the lift hill. SCBB Giant Dipper developed a similar kink after the 1989 Loma Prieta quake.
^^I don't think that was the case with Grizzly at Great America. And does Roar have any more wood that it's sister?
I know we've all heard that Ghostie's extra wood was for seismic protection, but is that really the case? The steel coasters here don't seem to have more steel.

I don't know that steel coasters require much more reinforcement seeing they pour the footers pretty deep for them. My guess is the steel is strong enough to withstand the shaking as most steel coasters are designed with some give in the first place.
