I agree with the others who say to not worry about it. There are about 3 coyote attacks per year in the US and Canada. 1/3 of those are due to people approaching or attempting to feed the animals. Given how many coyotes are out there, your odds of being attacked are near zero.
And, on a more general note, if you're afraid of coyotes, you should probably just sleep indoors. Personally, I love the sound of coyote howls, and if I heard a bunch nearby, I would fall alseep with a smile on my face, happy to know that local predator populations are healthy.
