I've never seen four raccoons together like this. And this was dusk. It wasn't even nighttime. (It merely looks a little darker because of the tree cover and the contrast with the flash.)
Luis and I also have seen a few skunks in the city. One time we ran across the street to get away from one, and he followed us across the street and started coming in our direction. Fortunately, we got away. One Vancouverite said he had to throw out a good leather jacket after getting sprayed by a skunk.
