I personally have had a coyote run across the front of my truck as I was returning from a late night class. This was in the inner sunset area near Grand View park. I thought that was the strangest dog I ever saw so I followed him. He ran up the slope of Grand View park( basically a hilltop green area). I drove my truck over the park curb and lit him up with my brights. Sure enough a large healthy coyote was staring back at me.
Ms. Fox in that article and those like her are many times quick to discount a possible coyote attack on people.
They do happen and I recall at least one attack and believe there were two on small children in areas of So California in the last 5 or so years.
