It is not uncommon for coyotes to attack at people, at least not up this way. Although it is not an every day occurance either. One guy a wood cutter was chased to his pick-up truck and had to jump on back of it. The only weapon he had at the time was a chainsaw. So he started it up and revd it and after a while the yotes left him alone long enough for him to get in the truck.. Mostly though coyotes leave people alone none the less..
