DMAP tags are doe tags and if there were as many hunters in 2g as there were during the 80's you wouldn't be getting 6 DMAP tags and you wouldn't be hunting deer that had experienced very little hunting pressure.
It is easy to kill a deer that hasn't been subjected to hunting pressure ,since they follow their normal patterns and are are lot less wary than a deer that has been pressured. The deer in our area are so pressured ,they don't even expose themselves in the off season ,which is why we see very few deer during the summer or fall.
