This was back in March or April. We went to the Tribeca Film Festival. It was pretty fun. Basically though, anything free in NYC is just completely crowded, which often translates to it being not that fun. There were some fun things for the kids to do, and a really cool park that the kids loved playing at after the festivities, and we met up with friends which helped it turn into a pretty successful outing.
Clearly, Nate was having a fabulous time. ;) He doesn't like crowds.
