If you are concerned about safety, have a light blaze vest you can wear and stash when you sit. I've hunted public land alot and never felt the need for blaze orange. I think most who get shot are already sitting and are shot when they make a movement by guys walking around. If you see someone coming, talk to them, so they know where you are. Sit against a tree bigger than you are, so someone can't see you til you see them.
