I hunted coyotes with a red light in Michigan for 3ish years and I was never able to call one in. I heard them every once in a while but the only thing I saw were deer. Once I moved to a thermal I not only started hearing them way more but I actually have seen them. Now whether I'm able to close the deal is a whole other story...lol. I don't see coyotes in the open very often. I've seen them on paths with tall grass where they have decent cover; not sure what it is but they hardly break cover. I know very few successful coyote hunters in person. Most I've ever seen have been here.
