Besides the obvious historical stuff.
She would more interested in shopping, water parks, amusement parks, etc.
Now, I would also be interested in the out of the way places, good food places, or little known historical places.
Our plan is to stay "in the area" for a few days after the event. Go to Gettysburg, DC, etc.
Any info on places that are a must see, or that the wife might want to visit when she gets bored would be appreciated!
