The best cheap target that will stop arrows out of even the fastest bows is easy to make. Being that you have horses, you probably have some grain sacks, if you can get a burlap one even better. Stuff it with old clothes (your wife probably has some you could use, to get back at her for the told you so. Just kidding don't want to get you in trouble) or I have a old sleeping bag stuffed in mine. Stuff it tight and close up the top. Spray paint some dots on it and you are good to go all summer. If I leave mine out in the weather all summer, I might have to replace the grain sack once or twice, give it a try! Oh ya almost forgot, don't shoot broad heads into it, they don't come out very easy.
