It rained the two full days we visited Gettysburg, so we took advantage of the indoor events, museums, tours, etc. Our tour bus was crowded, but the certified tour guide gave us a comprehensive tour of the monuments, facts about the Battle itself, etc. He had a thorough knowledge of the townspeople and how the Battle affected them during and after the 3-day massacre. We were struck by the loss of so many men's lives. There are wonderful monuments of each of the Union states, and you can drive by all of them on your own with an audio player or on the tour bus, as we did. If I had it to do over, I'd opt for taking our car so that we could make longer stops at each of the monuments.
