When I visited Gettysburg part of the trip was Business.
But we stopped by the visitor's center and picked up the self-driving tour, at that time it was a cassette tape,, Suspect it's a CD today.
You go to the spot on the included map.. Start playing and follow directions... Most interesting.... There was one problem later.
My daugher.. Much younger then..Well come that fall one of the things thy studied was the Civil war.. and naturally the Battle of Gettysburg.
Unlike the other students.. SHE had toured the battlefield.
Home is where I park it!
