University of Michigan students Natalie Eliot (left), Evan Keimer, Jackie Brand, and Caitlin Kozak splashed barefoot in the flash flood pond that formed outside their house on South Fourth Avenue. Later they helped push water-damaged, unstartable cars to drier spots higher up the hill and bought out their cooking pans to bail out the car of a mother trying to pick up her daughter from Pioneer.
