I usually have all of my stands up way before the season starts. But, there have been a few times due to stand location during the season I have moved a stand and hunted it the same day. Took a deer out of it that day. Usually I would give it at least a few days though and try and do it either just before a rain or in the rain. This will eliminate your scent rather quickly.
If I don't hunt the stand the day I hang it, then I like to wait at least a week. But like the previous post, most of my stands are already hung for this year. Better to allow time for the deer in the area to get back to their routine if I spooked them.
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.
