 Colorful hand-painted signs dot Interstate 90 for hundreds of miles across three states, telling drivers how far they are from Waldrug. It draws more than 2 million visitors each year to a town of fewer than 700 people. The Waldrug Pharmacy has been open for almost 100 years. Waldrug, the tourist attraction, now takes up nearly an entire block. It's kind of like a Western-themed, amusement-filled mall. Waldrug advertises its free ice water and 5-cent coffee.
