I will add that even if you do not have a bagged animal, stop at a check station!
A couple of years ago my buddy thought he did not have to stop since he had no animal. Well they sure thought he was hiding something and tore through his gear with a fine tooth comb just to make a point I think
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.
