In the Tri-State (South Dakota, Iowa, and Minnesota) area, one attraction scored extremely high on the 'tourist trap' index.

The label was slapped on western South Dakota's iconic Wall Drug 1,049 times, which makes it the world's number-two biggest 'tourist trap' behind only San Francisco's Fisherman's Wharf (1,050).

That hasn't hurt business much. More than two million visitors stop in each year to grab their free water and cheap coffee and doughnuts.

Wall Drug has been around since December 1931.
