Hayden Planetarium and Picnic in Central Park
On Friday we went to the Hayden Planetarium at the American Museum of Natural History, and then had a picnic in Central Park.
At the Planetarium we saw Dark Universe, an interesting albeit rather uninspiring presentation on Dark Matter and Dark Energy.
Then we went to Central Park to walk around Shakespeare's Garden, the Swedish Cottage, the Belvedere Castle, and the Turtle Pond. We chose a nice rock, and had homemade sandwiches for lunch, making sure we picked up all our (and somebody else's) trash on our way out.
