Wyoming no longer requires evidence of sex to be attached. So if it is an either sex tag you don't need it but if you have a tag that does require it you just cut off a little through it in a zip lock sandwich bag and you are good to go! Make things a lot easier when you are boning out a critter. A few years ago the Local warden in my town busted some Utah guys that had shot two bulls and a cow but only had one bull tag and two cow tags. They had left the head on the cow cut the head of one of the bulls and sewn the cows utter on the bull with fishing line.
