Also try to get a forest service travel map for the national forest you are planning to hunt/scout they are very helpful for finding pockets of land that may not be real crowded and it will keep you out of trouble with the rangers. you should be able to get them at any of the forest service offices. The only bad thing about them is they usally do not show topograghy.
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.
