20 yards but you have to remain very still, not make noise and have the wind in your favor. It's fun to watch the critters that close. They'll stare at you and try to bait you into moving. But if you remain still, don't make noise and they can't wind you, they'll move away slower instead of an absolute run when they suspect you're actually some kind of animal or person. It helps if your outline is broken up some but the wind will still bust you. Still a lot of fun though.
