Annual celebration of Farmington resident Chester Greenwood, the inventor of earmuffs. Greenwood was only fifteen when he designed the first pair of ear protectors out of wire, beaver fur, and cloth. At the age of nineteen, he acquired a U.S. patent. By age twenty-eight, the Chester Greenwood & Company factory was producing and shipping champion ear protectors worldwide. In 1936 the company had its biggest year producing 400,000 pairs. The day features a parade, road races, craft fairs, and family activities throughout downtown Farmington.
