More popular is the story that Stoskopf was a witch who practiced her craft out on Myrtle Hill Road, which today also has its own crybaby bridge legend. The story you hear most is that the townspeople put her to death.
Today her spherical tombstone is the focal point of a lot of folklore and legend-tripping. They say that it remains the same temperature, and that in the winter it is warm and in the summer it is cold. They also say that leaves and snow will not fall on or around the tombstone. These stories seems to be easy ones to test, and I definitely plan to check them out sometime soon.
