I have the good fortune to have an extra day on a business trip in Washington DC. I've decided I'd like to spend that day at the Smithsonian National Museum of Natural History.
Will one day be enough to take in all the exhibits and attractions? How long does the average person spend there?
My capacity to take in the exhibits probably exceeds the average user.
If not, are there parts of the museum that are more popular than others, so I can prioritize some things over others?
