(Radio Iowa) – The northwest Iowa town of Graettinger claims to have the state’s oldest Labor Day celebration, and another edition starts this (Friday) afternoon and runs through Monday night. Event co-chair Phillip Schmidt says the tradition had humble beginnings 127 years ago as a one-day event in a pasture with a tent and a traveling carnival. Schmidt says it’s grown to three-and-a-half days, now, with events including a golf tournament, a Miss Graettinger pageant, a truck and tractor pull, a large bake sale, and something called Cow Pie Bingo, where you pick a square on a field where a bovine may leave its mark.
