On a frosty Illinois pumpkin patch in October 1994, the owner and four hired neighbours each cut one row of pumpkins for a different order.
In October 1994 the first frost turned the vines silver on a pumpkin patch outside Peoria, Illinois. Halloween was two weeks away, and orders had come in from all over town. Dale, who owned the patch, pulled on a flannel coat and went out to cut pumpkins with four neighbours hired for the day: Hannah, Lucas, Rosa and Toby. Each of the five worked one row, and every row grew a different kind of pumpkin. They cut the thick stems with short knives and stacked the pumpkins in the wagon, and everything one person cut went to a single order. By noon the fog had lifted and the numbers were chalked on the barn door, but nobody had written down who cut what. Dale wanted it all sorted out before the trucks arrived.
