Gettysburg

Gettysburg needs 1 day: touring the battlefield at Gettysburg National Military Park, where the bloodiest battle of the American Civil War was fought in July 1863, with over 50,000 casualties in 3 days, and visiting the site where Abraham Lincoln delivered the Gettysburg Address, the same afternoon. April-June and September-October bring the mildest weather. It's inexpensive. Its battle marked the war's turning point in the Union's favor, and today the town preserves over 1,300 commemorative monuments spread across the battlefield, a density of memorials with no comparison at any other historic site in the United States.
