One begins to immediately spot advertisements for Wall Drug within just a few miles of the South Dakota and Minnesota border. Wall Drug Store was founded in 1931 by the Hustead family. It is essentially a western-themed shopping mall about an hour and a half away from Mount Rushmore. It attracts travelers by promising free ice water and 5 cent coffee through their hundreds and hundreds of billboards. There is also nothing around it for hundreds and HUNDREDS of miles.
