RE: plot saver?
I've heard that some folks have had success but it did not work well for us. I put it up and treated the ribbon and put a trail camera on it. The evening after I put it up the deer were already inside of it eating the clover.
I also put some around a little corn on the ground in the yard. At first it spooked them a little when it fluttered in the wind but they soon went right over it and ate the corn. Maybe the corn was too much of a tempatation for them.
