DC is one of our favorite date night spots. If you want to visit the places we went on dates, you can go to Planet Word, the National Air and Space Museum, the Postal Museum, Gravelly Point, the Botanical Gardens, and the National Portrait Gallery.
A "home away from home" for Dillon. While it is deeper south than our venue, if you have a time for it, you should definitely check out the beautiful rolling mountains. Try Hawksbill trail for a hike with tremendous views and stay until sunset at one of the overlooks - the views are amazing!
If you want to see our first date night spot (don't get robbed), then Baltimore is the place for you to check out. Our recommendation would be to check out the National Aquarium where Natalie and her family went as kids.
