How are they equipped for weather????

How exactly are coasters, especially large ones, and frefall towers, equipped for weather??? Like how good are they at withstanding tornadoes, or lightning strikes??? Another question, has a toranado ever wiped out a coaster???? I wouldn't think so, but you never know.

DOWN WITH TRIM BRAKES!

I don't know about tornados, but a number of Atlantic seashore coasters have been destroyed by hurricanes over the years.

Like, if MF gets struck by lightning, and the computer gets fryed, what happens???? Or, could all of the coasters at PKI handle a tornado head on???? I know it is obvious that riders wouldn't be on the rides when this happens.

Mf and many other tall rides and roller coaster are equipped with lighting rods(I belive that most rides and coasters have many rods). If the computer gets fryed they replace it or fix it(depending on how bad the computer is fryed).
