Photo provided GREENSBURG – Nearly 30 area farmers, friends and family all recently chipped in to take a Decatur County farming family’s grain to the market in Lawrenceburg. Taking an entire weekend to load, those involved formed a convoy to trek through the frozen Indiana countryside and deliver Dennis and Joyce Holtkamp’s grain to market. Donating their time, the convoy was formed from the goodness of their hearts. And the county sheriff saw his way clear to escort those making the trip.
