WINONA, Minn. — A driver, unfamiliar with the steep and dangerous crooks on Garvin Heightts Road, lost control near the base. Desperate to regain control, the driver pressed his emergency brake, which compounded the problem. The vehicle slid sideways through a grove of trees, rolled twice, and stopped finally on its roof in the U.S. Highway 61 ditch at Huff Street. Both occupants were taken to the Winona hospital. Police described their injuries as non-life threatening. A dog in the vehicle survived.This was about 12:45 p.m.
