Pack of Coyotes

I was sitting on the front porch of my parents house, about 2 or 3 years ago, smoking a cigarette. They live in a very urban/suburban area, with some woods nearby in the Renton Highlands. It was probably around 1am at night, when I noticed a bunch of animals crossing through the cul-de-sac which my parents live on. There were probably around 8-10 animals, which I recognized as coyotes, roaming around as a pack. They passed through at a brisk jogging pace, not even noticing I was there watching them go by. It was very unnerving and eerie to say the least. There was no one else around, and I was pretty freaked out.
