Hope the weather changes. It's been below -40 for a week. Physically holding one's place in line in such conditions takes some determination. But this type of thing tends to weed out people who don't belong out on the flats during the winter.
When calling coyotes, more often than not they will circle on a target they are
coming into and approach from the downwind side. Presumably they do this in
order to align what they smell, with what they are hearing.
This means that you should always have your downwind side camouflaged and have
an open shooting lane. If the area is heavily covered the coyote could come in
take a look and be gone, with you none the wiser.
