Planning our 4th of July trip- thinking Gettysburg

Thank you all so much for the input! Yeah I think we may decide to hold off on Gettysburg over the 4th. (You would think I would have remembered that was when the battle was fought being a history buff lol- just got caught up in the excitement of me and the hubby having almost 10 days off together) I want to be able to enjoy it and take in all that history without a bunch of crowds. Hmmmm now where to decide where to go....lol
