We stopped at the Corn Palace in Mitchell for a quick look. The Corn Palace is a huge civic arena that is decorated each year with corn and grasses. We started the last fifty miles to Huron before long the sky started to darken. The weather radio reported; torrential rain, seventy mile per hour wind gusts, hail and tornado warnings. Countering these conditions with multiple prayers we slowed down and kept going. Finally we arrived in Huron. As we entered town the road was blocked by a tractor trailer that had been blown over by the wind.
