Keith Miller has the best idea on here yet. Another way is if you have any venison flanks left over from over a year, set them out in a small whole or staked up, but make sure you set the meat out in the sun in a zip lock baggy for awhile to get some good aromas going on. Along with that method is to get a 3d target or deer decoy and lay it on it's side next to the meat and that will work also.
