The Parade

We just got home from NYC and let me tell you, we are pooped! I have lots of pictures of everything, but still have a few other things to do first.
So, for now, here is a fun little game (that I will complete when I post the pictures from today).
While we were sitting in traffic we played the state license plate game.

Can you guess how many different states we saw?

What states did we see?

New York and New Jersey are given, so I'll give you those two.
Post your guesses in the comments.
