I remember years ago I was working in a room in a office building and inside that room was all the phone equipment which needed power to operate. On the wall next to a door was a switch with a note above it which read "DO NOT TURN OFF". Well, a few months later I got a trouble call at that office building. When I got there I noticed that there was no power getting to the equipment so I started to follow the cords to a wall outlet. Everything was connected but then I notice that the switch with the note was in the OFF position. I turned it back on and my problems were solved. The next day the maintenance worker changed the way that the outlet was fed so that it didn't go through that switch.
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.
