We made it! After a couple attempts to visit the Civil-War-history-loaded Gettysburg, we finally explored it. We went to a museum with a short film and 360 degree show, the Battlefield, Roundtop Mountain and we climbed the rocks to have a nice view.
Afterwards, we explored the city a bit and had dinner in the Dobbin House, where we dived into the Middle Ages. They serve old-spelled Sandwiches, Dishes and whole chicken parts in a dim-light, rustic atmosphere with waitresses in Middle Age dresses. It was neat!
