12th New York Regiment Tower
On Little Round Top, you can climb a tower monument. One lady remarked that it was completely wrong to have built such a monument. I guess people were enjoying it too much, and you are not supposed to have fun where so many Americans killed each other.
You can see how beautiful the countryside is.
Visit Gettysburg National Military Park in Pennsylvania, between Baltimore and Harrisburg. 2013 was the 150th anniversary.
