What to do Columbus Day Weekend in Gettysburg PA

Land of Little Horses is kind of neat.Also,Pine Grove Furnace State Park isn't far. They have a small visitor center.It's the half way point on the Appalachian Trail.About a mile from the park are the remains of an old POW camp.They sell a book about that at the visitor center.They also sell a map that shows where all the buildings were.If you go to the site of the old camp,they have numbers that correlate to the map so you can see what was there.
