I'm looking at my Great Lakes region design load wind charts, and the area around MA isn't in any special wind zone. In fact, it's in the same zone as Cedar Point, which calls for a 90mph design wind load.
The other thing to think about is a typical wood coaster self braces. That is, a design which curves around upon itself is going to lend bracing support to the lifthill. Shivering Timbers is a very tall out and back, so there's no additional track structure to brace the hill...it must be braced on it's own. A good way to think about this is to take a playing card and try to stand it on it's long edge...it tips over because it has no bracing. Now bend the card so it curves a bit and try to stand it on it's long edge. Viola...it stand up without any additional bracing.
