When I wrote the following account of my experiences with rats, I lived in an apartment building on a block filled with other apartment buildings, amidst the approximately eight million people in New York City, and I paid rent to a landlord that I never actually met-though I did meet the superintendent, who was a very nice guy. At this moment, I am living out of the city, away from the masses, in a bucolic little village with about the same number of inhabitants as my former city block. I wouldn’t normally delve into my own personal matters, except that when I mention my rat experiences to people, they sometimes think I took extraordinary measures to investigate them, and I didn’t. All I did was stand in an alley-a filth-slicked little alley that is about as old as the city and secret the way alleys are secret and yet just a block or two from Wall Street, from Broadway, and from what used to be the World Trade Center. All I did was take a spot next to the trash and wait and watch, rain or no rain, night after night, and always at night, the time when, generally speaking, humans go to sleep and rats come alive.
