I have family in the Hudson Valley. We love all it’s historical areas. The places from the story actually exist and you can see them. Most of the characters in the story were inspired by real people. The Headless Horseman does haunt Sleepy Hollow (for those who believe the supernatural exists). Here is his real story:
He died in the Battle of White Plains in real life. His head was never found (it most likely disintegrated when the cannon ball hit him). He was an honorable hessian who fought on the wrong side.
