Every October in Keene, New Hampshire. Local families and visitors from afar are all welcome to participate by bringing a carved pumpkin to display at the Keene Pumpkin Festival. Rows of bleachers line the main street and hold thousands of jack-o-lanterns. And at the town square, a huge scaffold is erected to hold a tower full of pumpkins. Last year there were 16,186 lit jack-o-lanterns- quite a sight!
