Get National geographic topo cd-rom for wyoming. Also get surface management maps of the area you are hunting. From there, you can find sections on the cd-rom that correspond to the sections on your map. You can then mark waypoints with the waypoint tool on the topo software, mark them on your map, and type coordinates into the GPS. You can have waypoints plotted without ever having stepped foot in the area. I often do this to mark where public land starts, roads, section/property corners, springs, etc . . . I simply make a dot on my map and name the waypoint, then write the coordinates and name in the margin of the map, type it into the GPS with the same name and you're golden.
