A guy at camp where I hunt public land said that his friend had one growl at him, so he shot it. Maybe it had rabies??

I have seen coyotes in the woods a few times, and leave em alone. The other morning before sunup I heard a pack of them howling, which I thought was very cool. I have no reason to bother them. I know some guys shoot them because they think coyotes will impact the deer population, but I doubt it has much impact.
