For anyone interested in U. S. history, Antietam Battlefield is a must. To know this was the bloodiest one-day battle of the Civil War, makes you feel a quiet presence while visiting the vast grounds. Take One-Peter What I like about Antietam is the landscapes. The open fields. Trying to picture the thousands of men who were here. Going during the fall, there are incredible colors of the green fields and rolling hills.
