Sloughgrass entertains Saturday evening. Small entry fee. The main focus of the annual show is steam traction engines, tractors and other farm equipment of the early 1900s, but they also cover other aspects of life in that era. The annual show is held on the weekend of the first Sunday in August, 9 miles North of Roosevelt, Minnesota, on the Grove family farm, near the intersection of County Hwy 17 & County Road 50.
