I always pick up any trash I see, as well as my brass. I nearly got cross with a guy out there who was one of the brass poachers. This guy comes up with his brass picker and is literally sweeping up brass around my feet as I'm trying to shoot. I told him that this was all brass that I had shot, and that I'd be taking it with me. After I cleared my gun and put it back on the bench, I made some serious eye contact with him and told him to leave the area. He did. I've never seen someone so careless as to try to clean up brass around someone's feet as they were shooting, much less without asking beforehand.
