http://www.basspro.com/Ridge-Hunter-Archery-Bow-Holder/product/95154/ my ground blind had a hook hanging from the top crosspieces but never felt comfortable hanging the bow from it. thought at the wrong time the weight would collapse the blind. So I picked up a $10 bow holder from basspro that is a bent piece of plastic coated metal rod that sticks in the ground at an angle. worked fine except in the Florida sandy soil it would occasionally rotate and fall over so I clamped a piece of arrow to it so two give it two spikes sticking in the ground. Works great now. am surprised they don't make them that way. I'll see if I can post a picture later today
http://www.vegaoutdoors.com/ground-blind-stake-bow-holder-hang-tag.html here is a better picture of the bow holder. I used two small hose clamps to clamp about a 12 inch piece of arrow with a field point to the main straight section which gave it a second spike sticking in the ground and prevented it from turning.
