Ironwood, MI Today was one of those educational days. There are several claims to the World’s Largest Ball of Twine. The largest nylon twine ball weighing 13,000 lbs with a 41.4 ft circumference is in Branson, MO. The largest ball of sisal twine built by a single person, (17,400 lbs, 40 ft circumference) is in Darwin, MN. If we, instead, consider the largest ball of sisal twine built by a community, one would travel, as we once did, to Cawker, KS. Theirs is 20,100 lbs with a circumference of 43 ft. The heaviest twine ball, coming in at 21,280 lbs with a 69 ft circumference, is in Lake Nebagamon, WI, so we stopped to take a look. James Frank Kotera works at another job 3 days a week. The rest of the time he's usually home, adding twine to his ball. He's been doing it since 1979. His property is easily identifiable since it is decorated with duck decoys and other plastic birds stuck on poles. He keeps his enormous twine ball shielded from rain and snow beneath an open-air shelter, resting on cinder blocks. Unfortunately, JFK was not home when we stopped by.
