You know when places have high wind warnings and warn about flying debris? They aren't kidding. The Detroit area has gale force winds and my son-in-law walked outside. Flying piece of metal. He's still at the hospital.
Cartilage severed from nose, chunk missing from head, 25 stitches, and a gnarly scar in his future. All from a 6 ft piece of flying sheet metal ripped off a neighbor's roof by the wind.
