If you are a Civil War buff like I am, or even if you aren't, check out the Archives link on the website. I've been to Gettysburg, literally over 50 times, and I can't wait to go back again. The work they are doing to restore the field to it's 1863 appearance for the 150th anniversary is amazing. It's like going to a new battlefield each time I've visited the past five years. The new museum and its' restored 360 degree cyclorama painting are fantastic. Hook up with one of the guides at the visitor center to give you the basic tour or a tour of some specialized aspect of the battle you have an interest in. You'll be in for a real treat.
JFK's visit to Gettysburg...
On March 31, 1963, President John F. Kennedy with some friends and members of his family drove from a church service at Camp David, Maryland, to tour the Gettysburg Battlefield. Their guide was Jacob Melchior Sheads, a longtime Gettysburg High School History Teacher and seasonal historian with the National Park Service. Licensed Battlefield Guide Richard Goedkoop follows what we know of the route that the Kennedy party took around the battlefield.
