How do I make my own backstop?

[Big'n]

I might be wrong but I don't really think anybody was advising using Hay as a backstop. If they did they probably don't know what hay is. Hay is used for feed for livestock. Straw is used for bedding. It is Straw that you want to use not hay. Most city folk errantly call anything that comes in bales "Hay". With that said, the answer to your question is No .....the whitetail won't bother it unless weeds start to grow in it. Straw has no nutritional value. Hope this helps. DAVE
