The "Worlds Largest Ball of Twine," not to be confused with the "Worlds Heaviest Ball of Twine," or the "Worlds Largest Ball of Twine That People Are Still Adding To" is in Minnesota. I saw it once, when I was young, when we were driving my friends kid brother to a hockey game out in the middle of nowhere. That's where the ball of twine lives, near a water tower, in small-town-nowhere-Minnesota. It was very big, and anti-climactic. The towns folk built it a little house. I love that the guy spent his whole life saving bits of string until the ball became too big for his home, so he rolled it himself, to it's final resting place at the vista point near the water tower. An amazing collection of twine.
