The U.S. Bobsled Team won its first Olympic medals since 1956 in Salt Lake City four years ago. The turn-around is due in no small part to the philanthropic efforts of NASCAR veteran Geoff Bodine. He’s raised more than a million dollars to help make better sleds with American technology. Last weekend, Bodine invited other NASCAR drivers to race the Olympic bobsled track in Lake Placid. They brought their addiction to speed and competition, and their fame, to help boost the sport. David Sommerstein reports. (6:35)
