I wish I had to room for some bales like that. I agree that once the fear of the backstop goes away things improve. I have a heavy rubber matt behind my targets now. Its not a stall matt, thats next. But for now the rubber large matts at home depot are serving well enough. Not 100%, but with my arrows slowing down before they hit the fence I'm happy at least. Agree on covering it. Not to insult your intelligence, but year, wet hay goes away fast, plus it molds and rota and is an all around pain in the butt. If you can score a tarp you can cover all the sides except the face and you'll really stretch the life of those bales.
