Steve .... having to tag buttons with a buck tag would not be a good idea ... what happens when your buck tag is filled and you shoot a button by mistake??
BB are not that hard to identify.
Do a graduated fine - x for the 1st, 5x for the 2nd, 10x for 3rd etc.
Hunters would learn quick.
If they do mandatory AR in CNY and allow the slaughter of BB to continue, every antlerless I take on public land will have buttons.
Lots of public land around me and they are not hard to identify.
