Hunting on the 'cheap' is not that hard...Your firearm, good location with a Coyote population, a decent hand call, and if you want to give yourself a slight edge, find a couple of turkey or chicken feathers, tie them together on a piece of fishing line and hang them from a tree branch a little away from you for the animal to lock onto with his attention while you are calling..
Enter your location with the wind in your face and set up where you have a cross breeze and watch for them to come in from your down wind side...Other than that it takes practice, patience, and perseverance,,,,You will learn something new every time that you maybe should have done, or could do better...
