Caption only: Old school buses provide defense against Canadian floodwaters

Canadian floodwaters A milelong row of derelict school buses, wrecked cars and round bales sit on a side road near Brunkild, Manitoba, Canada, on Wednesday. The vehicles are intended as a breakwater for a 25-mile dike being built southwest of Winnipeg. Three thousand families and businesses in the province are on alert to flee within 24 hours if the Red River crashes through the dike.
