A front-end loader dumps snow in to a truck as workers remove snow from the field of TCF Stadium, home of the University of Minnesota's football team, Tuesday, Dec. 14, 2010, in Minneapolis. The Minnesota Vikings said Tuesday they're getting ready to use the stadium as a backup if the torn Metrodome roof can't be repaired before Monday night's game against the Chicago Bears.
