My pigeon "box" is a barn and my neighbors are delighted when I shoot as they are pests in a horse barn. My technique is to stand outside in the shade of a juniper and throw a rock on the tin roof of the barn, The pigeons come out circling and I get my shots. They often come back after about fifteen minutes and I get a second shot if they don't see me. It is great fun and not considered murder. The trouble with organized pigeon shoots is that the bleeding hearts have an event they can point out as heartless and since I hunt by stealth there is no public notice. David
