CENTRAL CITY, Iowa (AP) – Linn County Fair leaders celebrated the opening of a new building at the fairgrounds in Central City on Sunday. The Lynn Dunn Memorial Building is dedicated to Lynn Dunn, a Marion man who worked at the fairgrounds before passing away from a heart attack in 2008. Lynn’s son, Ryan, says cutting the ribbon for the building was a surreal and bittersweet moment. He says he’s glad his father’s memory is being honored by the building. Linn County Fair leaders say Dunn had always dreamed of a place people could come to for year-round events. They say grants and private donations helped pay for the $875,000 building.
