It's been so long since I deer hunted down in Texas with Dad that I don't even remember the law that you described in your post flags. I wonder if the reason behind that is because of so much of Texas being private land and that's one way the GWs can check a person when they hit a highway with their animal. Until a few years ago Wyoming required that evidence of sex remain attached to a decent size piece of boned out meat. Then they changed it to just having evidence of sex with the carcass pieces, so now we just bone everything out and put the udder of a doe deer/antelope, or cow elk in a ziplock bag and we're good to go.
