A New Pre-ski Sport Launches a Following

Rocketing down a ski run used to require snow. But before you break out the winter boards, hop a new pre-ski mountain sled at Park City Mountain Resort in Utah through mid-October. Navigating the nearly 1,300-foot drop down Homerun, drivers control the brakes and steering on the motorless four-wheelers that resemble soapbox derby carts. Headfirst descents on these modified thrill sleds produce skeleton-style chills — with or without a parka. (800) 222-7275,
