Every hunting season, I live on 80acres of woods and swamps. Mountainbike all summer, heat with wood that I cut from our woods, and hike in there almost every day. I see and hear coyotes a lot. I am not a stranger to the forest or woodsmanship, Have hunted, trapped and fished since I was about 6ish so I spend a lot of time in the woods. When we hunted coyotes in the midwest we did it at night usually, still no packs. I personally have never seen a pack of coyotes, don't mean to discount anyone's real-life sightings of coyotes packs. I just don't believe they are common. I have not encountered a coywolf yet that I know of.
I guess they pack up more in urban environments?
