Mike Garon, right, of Washington Township and Bill Schmitz of Commerce Township paddle a racing canoe upstream in the Huron River at the Island Lake Recreation Area Saturday. With cold temperatures settling in, (21 degrees at noon Saturday) this is one part of the Huron river that never freezes. They are preparing for the AuSable Canoe Marathon, a 120-mile race that starts in Grayling and ends in Oscoda. (MARK BIALEK/Special to the Detroit News) - Ann Arbor Photography Mark Bialek
