I figured since it is July 1st, maybe folks can share things related to the battle if they'd like to.
I started watching the NPS' Gettysburg Battle Walks and have found them very enjoyable. One in particular related to Robinson's Division on Oak Ridge presented by a Park Ranger, John Hoptak:

Everyone, feel free to share/add something!
