Wow! It was amazing to see the Gettysburg National Military Park. I had heard from several people how powerful it was to go through the exhibits and visit the battlefields. I bought a ticket to do everything. I watched the movie, viewed the circular painting of the battle, and went on the bus tour with a guide reviewing the three day battle.
My tour guide spent 30 years in the army special forces, so he especially enjoyed telling us about the respective army strategies and high terrain and it implications. I spent more than 7 hours going through everything and I think I only touched the surface of what is there.
I highly recommend a visit!!
