Finally made it to the American Stories show at the Met today. Wonderful fun. I highly recommend it, especially with the museum's audio guide. I think going through this show takes around 1 to 1 1/2 hours with the audio, and it will be there until the end of January.
Amazing examples of American art - for a few striking examples: Copley's Paul Revere, Eakins, George Bingham, plenty of Charles Willson Peale including the one showing his mastodon skeleton, and lots of great Winslow Homers including Gulf Stream:
My advice to anybody visiting the Met: Pick one thing to see. One permanent exhibit or one temporary show. Go straight to it and, after that, leave. Do not get distracted or drawn into other things or you will end up with the brain-numbing surfeit of images and information to which I refer by the term "museum brain." You can always come back.
