Beyond the cattle barn, the "oink booth," the haunted house and meat-on-a stick, the Minnesota State Fair has a new attraction this year.
Tucked away in the education building at the fairgrounds near St. Paul is an exhibit featuring something anybody would love — free dough.
"How often do you get free money? Genuine U.S. currency," shouted Karmi Mattson, who manages public programs for the Minneapolis Federal Reserve Bank, which set up its first-ever booth at the fair.
Sound too good to be true? Yup.
