That stuff is cool, but nothing has ever blown my mind like seeing the spruce goose. It’s at the evergreen aviation museum outside of portland, and it’s impossible to believe how big it is.
Fly into New York City. Visit museums there for several days. See a Broadway show. See the Intrepid.
Take the train down to Washington DC. Several days at the Smithsonian there, including a trip out to the Udvar-Hazy Center. Take a day trip by train to Baltimore to see the National Aquarium and the Maryland Science Center.
Rent a car, drive to a beach town in Virginia for a weekend; drive back and take the train back to NYC. Or, drive up to a Delaware beach instead and return the car in NYC.
See the other museums in NYC that you missed the first time. Fly home.
E.g. Natural History, Air & Space, etc.
Growing up in the DC area has spoiled me for museums. They're high quality and generally free admission.
Second this. Glad to see that it's still open. I was last there sometime in the early 90's.
