After a year off, the Wisconsin Farm Technology Days event returns to a farm field in Eau Claire County starting today (Tuesday). More than 500 exhibits are planned for the three-day event. Organizers say it took more than two thousand volunteers to make Farm Tech Days a reality. It’s being held at Huntsinger Farms just outside Eau Claire. Opening ceremonies will begin this morning (Tuesday) at 9:30 a-m. It’s called the largest agricultural show in Wisconsin.
