The woman who was injured while volunteering at a snowmobile race at Giants Ridge ski resort on April 2 remains hospitalized, but her condition has been upgraded.
Natalie Suzanne Lindberg, 22, of Big Lake, Minn., was listed in serious condition Tuesday at St. Luke's hospital in Duluth. She previously was in critical condition.
Lindberg was volunteering as a scorekeeper at the World Snowmobile Association's "Twisted Chaos Series" race on April 2 when one of the racers fell off his snowmobile. The snowmobile veered off course, and when Lindberg tried to step out of the way she hit her head against something.
Lindberg was volunteering for Scheer Madness Motorsports of Plymouth, Minn., which was staging the event. She had volunteered for the company for four or five years, according to Wally Scheer, the company's president.
