It was a sunny and very cold winter day. The semi-truck had been slow to start but it came around. Clay drove along the gravel road to the highway. He was hauling a load of corn from the previous fall. He would take it to the co-op about 20 miles away to sell it. The last big snow had been a week ago. The ground was covered but the roads were clear. In this part of the state the land rolled gently up and down. Clay was expecting a routine trip.
