We also stopped to have a full 3 kid cry fest when we found a tiny baby rat and I would not pick it up and bring it home with us. There was no way I could save it, so we had to leave it. It will likely be the one thing they remember from this trip. Nice.
A highlight was The Evolution Store a great shop that sells insect specimens, human skeletons, meteorites and other sorts of oddities. (They have a great online store too!). David and I had gone over 10 years ago and loved it. It is amazing that we now have children who love it as much.
We ended our day by squeezing into a too small booth and enjoying ice cream sundaes at The Three Star Cafe, a neighborhood greasy spoon.
Tomorrow, David is taking the kids to the park (the big one) and I have a conference. If all goes right, we will spend the afternoon at the Met.
