I wanted to post back earlier regarding my comments about how VA does it. My question is are you talking about people who don't tag the deer at all or just the ones who don't send in their cards? If you are talking about people who don't tag their deer at all, there isn't much you can do about that. But for the people who do tag their deer and don't send their cards, the VA phone in system would def work. There is no physical tag you put on the deer but your license has 6 lines for deer tags and a notch to be cut off. you get 3 buck tags and 3 doe tags. The deer is not tagged until you call it in and get a confirmation number. You can not take a deer to the butcher with the number.This would solvethe problem for people who don't send in their tags. Now if you are talking aboutpeople that don't tag the deer at all and just shoot them and take them back to their house for butchering, then there really isn't anything you can do about that. Hope this helps!
