FILE - Ths file photo taken on May 6, 2009 shows the exterior of Wall Drug in Wall, S.D. Wall Drug is a sprawling attraction in the tiny town of Wall, South Dakota, with a drug store, gift shop, restaurants, a chapel and several other stores. Pharmacist Ted Hustead bought the drugstore in 1931, but business was slow until his wife suggested advertising free ice water to parched travelers. The water is still free to tourists enticed to stop here by signs on Interstate 90 on the cusp of the Black Hills. (AP Photo/Carson Walker, file) less
