If you’re in the NYC area, go check out the Carts of Brooklyn racing association’s shopping cart races…
“The Iditarod is the famous long-distance race in which yelping dogs tow a sled across Alaska. The IDIOTAROD is pretty much the same thing, except that instead of dogs, it’s people, instead of sleds, it’s shopping carts, and instead of Alaska it’s New York City.
The fourth annual event happens January 27, 2007. Teams of five will race for cash prizes and glory.” – Link.
