I sort of remember the story about how the tradition of carving Pumpkins started. In Europe they used to carve Potatoes or Turnips. And the reason was to keep away evil spirits.  They'd carve a scary face and leave the potato or turnip in the window. And Europeans brought the tradition to America and we have pumpkins. So voila.

Here's the link to the History video I watched. My guess is most of us don't think about anything historic about carving pumpkins. It's just something we do when you have young children. Jack O'Lantern reporting.
