5. Gettysburg Battlefield in Pennsylvania
This one goes without saying: The Battle at Gettysburg, Pennsylvania was undoubtedly one of the bloodiest in all of American history. Many of the 50,000 young men who died over the course of those fateful three days never got a proper burial, and some say they still wander the battlefield to this day. One thing is for sure, we wouldn't want to be out on that field once night falls.
