COLORADO SPRINGS, CO— Two weeks after returning from the Salt Lake City Games, U.S. Olympic skier Courtney Roth, 31, found herself staring down the icy, forbidding slope that is her future Monday. "I got an offer to do a supermarket opening in Denver next week," Roth said, "and it looks like I may sign on to promote the new popcorn shrimp they've got over at Lou's Lobster House." Following several months of three-figure endorsement deals, Roth will land a job in Vail teaching skiing to surly, spoiled 5- to 10-year-olds for the rest of her life.
