They are interesting creatures. I came home from work one day to find one sitting under the front kitchen window. BIG F'r! I didn't even see it at first. It was sitting under some bushes next to my front door, and as I went inside I caught it move out of the corner of my eye. Second guessing myself I went around the house back to the street to get a "for sure" look. It just hunched under the bushes staring at me. I called animal control and they wanted me to shoo it away by throwing rocks at it..
Mind you, I live in the city. There is a small mountain park near by, but it would've had to cross at least 6 lanes of busy traffic, through a neighbor hood, and into my cul-de-sac in the middle of the day...
