It is really a must when you come to NYC, although it is not the best Natural History Museum I've been to.
You have to try one of their exhibitions - they are amazing!
And of course - lying under the big Blue Whale and wondering if it is going to fall and crush you. Or is it just me? ;-)
The Hall of Biodiversity is my favorite room! It is amazing!
