Dr. Paul Sando assisted in the placement of the largest Geocache in Minnesota (and possibly the largest nationally) right here in Moorhead! The cache is part of the historic Probstfield Farm properties. The Geocache is part of a nationwide set of new cache sites set to go active on Sept. 28. This also happens to be the day of Probstfield Farm’s Harvest Festival. Come for the Geocache, stay for the fun, activities and food!
