Maryland:
1) Allow Sunday hunting all year, state wide. Although this is a legislative issue and not something DNR can change, they can certainly help promote the idea.
2) Make mandatory an archery proficiency test (taken from another poster). There are far too many folks hunting that can't shoot worth a darn. Here on our Navy base, we have to qualify to hunt. In talking with the guys to do the qualifications, you'd be shocked at some of the shots folks take and think are good "kill shots" that are not even close.
3) There are more, but they have already been said.
