Love it or loathe it, you can't ignore Wall Drug, not least because of the dozens of signs that announce its existence from miles away. The original signs were erected back in 1936, as owners Ted and Dorothy Hustead used the offer of cheap coffee and free ice water to tempt travelers to their drug store in the small town of Wall. Today, the store is so tacky it's brilliant, with dozens of specialty stores and a collection of novelty items from fiberglass dinosaurs to animations that can be activated for a quarter. It's not subtle, but makes no pretense to be.
If you go:
Yes, they do still offer free ice water and coffee at 5 cents a cup.
