Last night (10/1/10) there was a caller from Maine talking about the Bucksport "boot" on the headstone. He is correct. I also live in Maine and have driven by it many times, especially as a kid when we would drive up to Northern Maine to see my Grandmother.
As the story goes:The grave of Jonathan Buck in Bucksport, Maine has a footprint stain in the tombstone. The tombstone has been replaced many times but the foot always reappears a short time later. Jonathan Buck ordered the death of his mistress, claiming she was a witch. She promised to return and dance on his grave. It is believed to be her foot (and leg) that continues to appear on the tombstone.
