If you are bow hunting pronghorn you will need to consult others, as I know little of bow hunting. I gather, however, that a common strategy for pronghorn hunting with bow is to set up near a water hole expected to draw pronghorns for a drink, for example in some kind of blind. I read stories of bow hunters sitting in their blinds, baking in the sun, until a pronghorn approaches within shooting distance. Pronghorn have exceptional eye sight. Others suggest you can lure pronghorns closer by appealing to their curiousity, such as waving a flag or placing a light jacket on a post which may flutter in the wind. Maybe this would work for bow hunting, placing yourself off to the side, between the pronghorns and the fluttering jacket or bandana. If you are bow hunting be advised, also, of the high winds that are common in Wyoming. Lots of wind.
