Rats ...

On my train, I often see egrets, ducks or Canadian geese in the waters of the Meadowlands between Newark and Weehawken, N.J.

This evening, I saw what I'm pretty sure was a rat swimming in a (probably) polluted bit of water near the tracks.

I was initially surprised, then realized it was more surprising that I had not spotted a rat in the 2 years and three months I've been riding the rails from New Providence, NJ, to New York.
