Here is a safety tip for all of you Non-Iowans out there.  If you are going to Adventureland which is an amusement park in Altoona Iowa and are going to ride the "Silly Silo" which is a ride that spins guests around in a large cylinder as they become stuck to the walls while the floor drops out, don't take any Red Bull before you get on this ride!  Take it from somebody who has ridden this ride, nobody wants to see a person upchuck at 100 mph all over the place unless you are Linda Blair!
