I recall a recent thread about targets with some good ideas tossed around. I was wondering what folks use for back-stops? Basically, what are you relying on to stop your arrow in the event you miss the target. I know a natural hillside, sand pile, etc are likely options. I'm just not impressed with bales of hay. Of course there's the other obvious answer: just buy a bigger target! However, I'm looking for something to keep from sticking some field points into my board fence. I've made the commitment to switch to traditional archery, and I know I'm going to miss the target (maybe lots) until I get proficient. I've seen the big rubber "strip" back-stops they have at the Rabbit Creek archery range. Those work well, but man are they tough to pull an arrow out of. Any other ideas? I was thinking perhaps an old, really heavy duty canvas tarp doubled over....?
