I chased a coyote today. I was coming back from a bike ride and I found him in my driveway. He ran, but he looked back, as if to say, "What is your problem?"
I've got an old, sick dog around here, so I had to chase him, and I have chased other coyotes while on the bike, which they can't outrun. I stay out of mountain lion neighborhoods, and I don't find them in my driveway.
