Special Events of Note
September and early October bring the last of the outdoor festivals and events. They center around the apple harvest and of course pumpkins! Perhaps the most exciting is the Fall Pumpkins Weigh-offs. Often included in a fall festival, pumpkin weigh-offs put pumpkins on display. You can almost hear the thud as pumpkins, often weighing well over a ton are placed on the scales.
