Visiting this museum is a very humbling experience. It reminds me of how much I don't know, and how much there is to still learn.
Example - there's a fish, the coelacanth, that has not really experienced any evolutionary change in 380 million years. That's 380,000,000 years! To put that into perspective, humans (Homo Sapien Sapiens) have only been around for 100,000 years.
The students took as much in as they could, whether it was studying the dinosaur displays, eating crickets (yes, a student actually did this - apparently it tastes crunchy and mostly like the sour cream and onion flavouring), and enjoying some shopping time in the gift shop.
Lunch was consumed in food court of the Rockefeller Centre. There were a variety of options, but seating wasn't easy. In New York, if you see someone get up from their seat after their lunch, and you want that seat, you had better go after it with the utmost haste because if you hesitate.... Too late. You missed it. In NYC no one seems to concerned about if you have to stand and eat.
