Used to make good decoys in the old days by using black nylons over a shaped coat hanger to look like a crow. Open up the hook and stick it in the ground. They worked very good, but decoys are available now that work better. To get them on the ground, I find an open wheat field, set one owl decoy on top of a distressed flat decoy that is spread out, and place 3 standing decoys not far away. Dig a small hole and place the Fox Pro in it and cover it with burlap. Several crows will always land and you can bust them with a rifle from as far away as you want to shoot or the field allows. This even works w/o a caller, just takes more time since the crows must make a visual on the set to respond. I can usually fool them about 4 times in a day before they wise up.
