Wall Drug, in Wall, South Dakota, is among of the most interesting (and most kitschy) places in the west. It remains a "must-stop" for anyone heading west to Mount Rushmore. Originally, Wall Drug was just a tiny drug store... then they began offering "free ice-cold water." Well, lots of places would give travelers free water, but Wall Drug advertised that fact far and wide with a huge number of clever road signs. The result was an incredible boon--now Wall Drug is a monstrous Disney-esque attraction that has taken over much of the town.
