Gettysburg (and Vicksburg too)

First off, can do without this heat. Anyways, as shown repeatedly on C-SPAN weekend, we are in the midst of the 150th anniversary of the Gettysburg battle and the fall of Vicksburg, part of the fight against slavery (the "but for" cause -- h/t a comment at the link -- of the Civil War). And, some on Seneca Falls, which is not totally unrelated. And, Happy 4th!
