How Sledding Became an Extreme Sport
The Rocket takes sledding to the extremes.

On mountains across the country, thrill seekers are flying off cliffs, traversing through trees and doing flips in the air. All with a piece of plastic strapped to their legs.
It's not your father's snow sled. It's called the Mad River Rocket and some users are taking this sled to the extremes.
"What they do is totally amazing. It might be the most proud I am of inventing this," said Dave Sellers, who has never done a flip on his Rocket.
Twenty-five years ago Sellers and some of his architect buddies wanted to have some control as they slid down the snowy hills of Northern Vermont. They also didn't like the idea of sledding face first, downhill, toward trees. Years of prototypes followed.
Early efforts required some rather whacky attempts to form a sled shell. "We took apart old electric ovens" to make a plastic forming machine says Jim Sanford, one of Sellers collaborators.
Finally, they came up with a couple solutions.
First, they decided to kneel on the sled and strap their legs down. To gain control, Sellers developed what he calls a "negative keel." Think of half a tube running down the bottom of the sled. That "keel" creates a monorail of snow.
"It makes this ribbon that is strong enough to hold you, and then you shift your weight and break the ribbon and go the other way . And bingo! We had it," said Sellers of his invention.
Rocket riders use their hands to turn the sled left and right. Sellers has dubbed this "free sledding."
In the last couple years the sled has been flying off store shelves. Seven thousand were shipped out this year by the Whitney Phillips, the president, chief assembler and shipping department of the Mad River Rocket Co.
The former competitive skier is a one-man Rocket representative and an extreme sledder in his own right. He faced the same sledding problems as the Rocket's inventor.
"I had no control as a kid and this one is just like skis or a snowboard. You can cruise right through the woods," said Phillips. And cruise he does with friends — darting between trees, even jumping off rocks.
