I have to agree with those who say you were in no danger. I recognize the area where the photo was taken, and can tell you it is almost certain no coyote will attack you within a 500 mile radius of the place (I've never even heard of a coyote attacking a dog, but this is a very redneck town). Thank rednecks and hunters, who have virtually free reign to shoot any coyote at any time for no reason anywhere so long as it does not jeopardize human life or property. In fact most hunters and ranchers, who are far more numerous than BPL'ers, recommend shooting coyotes at every opportunity, and routinely go hunting specifically for them. I saw a coyote today at work, he was running away so fast at first I thought he was an antelope. Even if you aren't carrying a gun, a smart coyote assumes that you are.
So in summary, in the western US, excluding a few yuppie pockets, coyotes will avoid you by a good margin, and hide quickly if they see you. I don't believe there are any sufficiently yuppy pockets in your area.
