The show in Sioux Falss used to be the third weekend in Sept but about 3 years ago they mooved it to Aug. They had trouble getting good weather in Sept is why they moved it. By the way the coldest we have gotten this year is -33 on new years weekend. We had a couple of weeks in Jan that our high never got above 0 and lows were -20s to -30's. It keeps the rif raf out! One winter here and they tend to move on. Ha! Ha! Maybe we will see you in Sioux Falls this year.
