If I could waive my magic wand I would love to see NPS donate all of Jones Point in Alexandria VA for the museum. Sure, the Woodrow Wilson Bridge would split the campus, but you could park just almost anything that floats with a little dredging and infrastructure. Keeping the old light house there would add some ambiance and there is plenty of room for a massive building. The views would be good the access is easy. But, since I am waiving magic wands, I guess I would have to raise it a foot or so for potential flooding. All my goofy dreaming aside, I would love to see a NMUSN built.@squorch2!
Interesting idea. Anacostia Park would also work, I think. Also owned by the NPS, directly across the river from the Navy Yard. Adjoins but outside JBAB so you have security at hand but not restricted access. Maybe run water taxis across to the Navy Yard and Nats Park.
