Walter Douglas and Christopher Sylvester of Mechanical Systems brave the frigid temperatures Dec. 7 to repair a water main break on Bonisteel Boulevard on North Campus. The break that affected water pressure in the School of Music, Art & Architecture Building, Pierpont Commons and the Chrysler Center was repaired by early afternoon the next day. The temperature in Ann Arbor was a bone-chilling 1 degree when the break was reported about 9:30 a.m. (Photo by Lin Jones, U-M Photo Services)
