I wish I had seen this thread before I went for the first time this weekend. I just got back an hour or so ago. Absolutely fantastic place! Lots of adventures, and I ran into some reenactors on Cemetery Ridge and got some great photos.
Dude, you can turn to Freepers for anything!
Knowing our time there was precious, I turned to FR for tips and guidance. Got us the right breakfast in the right place. Then, bought the 2-CD auto tour (you play it in your CD player), and did that, all across the battlefields, and seeing everything from days 1, 2 and 3. Considering how short our time was, I feel we used it the best way possible. Can't wait to go back.
By the way, wasn't the village, around the square, one of the nicest little towns you've ever seen?
