One of Rock County’s largest and most historical events will not be held this Labor Day weekend. The Board of Directors for the Rock River Thresheree posted on Facebook the 64th annual reunion is cancelled. The post does reassure fans the Thresheree isn’t going anywhere, and is in the best financial position ever. Key concerns cited were the health of spectators, volunteers, and participants, as well as a desire not to put on anything but a top notch show.
