A Thrill Ride

So I was sitting on the front porch, having coffee and a sandwich. Suddenly I heard this loud kind of whirring sound coming down the hill. The next thing I know, three guys come down the hill, doing at least 25 MPH, riding on skateboards - on their BACKS! Whaaaaaa? I couldn't believe it, because I could not imagine how they would stop, for instance if they discovered a car coming UP the hill! Yikes. It gets better... 5 minutes later, a jeep comes up the hill, with the three guys riding upright on their boards and clinging to the car. So then I went and got my camera, and ran out to the street, looked up, and saw that two of the guys were getting ready for their second run. I was ready. Does this look like fun to you? Uhhh... It does not look like fun to me.
