Yesterday's thrill in Glenwood Springs, Colorado was an unexpected one. We boarded the Swing Shot at Glenwood Caverns -- the swing is 1,300 feet above the Colorado River, and after they strap you in, they pull you pack with a giant rubber band until you are almost laying down. Then the slinshot is released and you launch into the Glenwood Canyon. They say you reach speeds up to 50 miles per hour, as you swing out backwards over the canyon. I will tell you from personal experience that this is the scariest freaking ride.
We also rode the canyon flyer, where you race 3,400 down the mountainside, between the trees, and fly around the curves. Using levers, you control your own speed as you race down the steel tracks. This alpine coaster is apparently the first in the United States, and it was way way less scary!
