On our visit from Europe we visited Gettysburg National Military Park and had a personal guide in our car. This was the best decision ever. Chris - our guide - was enthusiastic, dedicated, extremely knowledgeable, knew a lot of back ground story, dedicated a lot of time to our questions without minding the time. He was just perfect. So I would really advise to take this opportunity to learn much about history. The Visitor Center was excellent and we really enjoyed the movie and the Cyclorama. Go and see it is really worth wile!!
