I have a blind that I set up, took 2 weeks. First I put out 4 old christmas trees facing down the creek bottom overlooking a scent rock.
Then a week later I put the blind up behind the christmas trees, used the trees to break it up a bit.
Then I staked a deer carcass down in the creek bottom near the piss rock. I now have seen 6 different coyotes at 35yds. None of which knew I was there, including the 35# female I shot last Tuesday. You need a reason for them to frequent a close distance to the blind. I also do not use a light, so the carcass is on the north side of the creek so I have good snow backdrop at night.
Just my setup. It is my first but it is working so far. I would not try and pack it in/out everytime. I leave a lawn chair in it which makes the long hours nicer.
