Same argument could be laid out for seatbelts, helmets, liquor sold by serving in public places etc etc. I still say it's nearly impossible to enforce but do it anyways. It affects us all, healthcare costs, time/energy/resources of emergency response personnel, and most importantly our loved ones. OSHA requires it in a workplace, some draw hunts require it on their properties.....TSA requires them with new stands.....impose it. Bluntly if I needed to call 911 for a emergency with my son and all medical resources are tied up with a non tied in hunter, I'd be upset. Very far fetched and extreme of which I know both patients would be equally important however I'm just saying!
