Not much is required for a good Zip Line course. A few high-altitude hills or trees. Some poles stuck into the ground. Wire. Harnesses and helmets. That's about it. Nice views are a plus, but optional. After all, when you're flying through the air at 45mph, looking around isn't a priority. But the mountain vistas on display during our run through Silver Streak's course were too beautiful to completely ignore. Most of my zips went like this: terror ("WAGHHHHHHH!"), admiring nature's beauty ("AHHHHHHHH!"), and back to terror ("AAYYYYGGGHGHGHHG!").
