I love the coyotsicle.
My boss is a trapper, and he makes his own rancid mix that he says really lures them in.
In the fall when you shoot some ducks, geese, or chickens, take all the spare parts and put them in a pail. Put the lid on the pail and leave it out in the sun all year long.( you have to prepare a year or so in advance) What you have left is a thick past that you have to stand up wind of.(or certain barfing)
Just keep adding to mixture for the following year. He says that there is nothing better???
