Thanks for the advice John.At the time I didnt really think, I just wanted to get out of there. It didnt really seem to of noticed us, or at least didnt look at us even though my dog barked quietly. Next time I will be sure to stuff my pockets with gravel to throw.If the coyote hit passing gear when it noticed you, you have nothing to worry about.
Regardless, running from a predator is not a good idea. That makes you prey in it's eyes.
If a coyote doesn't seem to fear you, pick up a fist full of gravel and/or a stick and walk normally. If it approaches, give your best low-pitched loud growl and throw the gravel. Immediately grab more gravel and face the varmint, acting like you want to fight and hollaring for it to "get out". Predators don't want to fight, they want to eat. Fighting gets you hurt. They will almost always retreat. Look for a stick. Next time, carry a weapon.
