Which of these US states has a museum dedicated entirely to potatoes?

The Idaho Potato Museum is a museum devoted to the potato, located in Blackfoot, Idaho. Exhibit displays are donated from a combination of community and commercial sources. One of the most popular displays in the museum is the world's largest potato crisp, donated by Pringles of Procter & Gamble. The museum's exhibits include the world's largest potato chip, measuring 25 by 14 inches, and a timeline history of potato consumption in the US (including the introduction of fries to the White House menu selection during the presidency of Thomas Jefferson). Also on display are Peruvian-made 1,600-year-old vessels that are believed to be the first containers used specifically for potato storage. A Hall of Fame acknowledging significant contributions to the potato industry is also an ongoing feature of the museum.
