Mainstreet Radio's Tom Robertson interviews and reports on two Bemidji sisters, Kari Erickson and Stacey Liapis, on going to compete in the Olympics as curlers. If there is a curling capital in Minnesota, it may well be the city of Bemidji. The winter sport took hold there in the 1930s, and the community has embraced it ever since. In the past two decades, Bemidji has produced 20 national championship teams. This year, two Bemidji sisters -- coached by their Dad -- will compete in Salt Lake City for Olympic gold.
