A healthy serving of history will be on the menu this week when the Iowa Department of Cultural Affairs and the Healthiest State Initiative team up to offer a walking tour of historic sites at the Iowa State Fairgrounds. Iowans are invited to join leaders of the Healthiest State Initiative, Lt. Governor Kim Reynolds and other state officials at 8 a.m. Thursday for a 1K historical walking tour of the Iowa State Fairgrounds, beginning near the Department of Natural Resources Pavilion on the Grand Concourse, just east of Gate 11 near East 30th Street and Grand Avenue. The half-hour tour will end near the new MidAmerican Energy Stage in time for the 2015 State Fair opening ceremonies. Each participant will receive a “history on a stick” fan filled with facts about sites on the tour.
