I think QDM is great and I practice it on my property but it's not something you can force on others. I have posted the 50 acres I have to ensure those who have access know the rules.
...I guess you don't hunt New Hampshire. Sure must be easy to let 8 pointers walk when you have that many deer. If we let any deer walk (and a lot of us do), then there is no gaurantee you'll be eating venison.
I practice QDM in NH and in Maine. I understand you point about the 8 pointer as there aren't a ton in our woods. I luckly have the option to take a doe on an additional archery tag and the land I hunt in Maine is in an extended archery zone that allows me to take about as many does as I care to buy tags for. I'm starting to see the results of letting little bucks pass forks, basket six, and even the occasional 8. I know alot are shot durring the firearm season and that is out of my control (until I get my 5000 acre ranch) but to get access to my land you've got to play by my QDM rules.
