NR hunters DO have a huge impact. I used to hunt Maryland and the PA hunters (Better shots, I guess) destroyed that area I hunted. It was a good deer populated area that had a lottery for NR doe tags. Once they allowed liberal doe hunting in that area it ruined it. I hunted there for years and hardly saw any PA plates. Once they opened up more doe tags it looked like the circus came to town.
I noticed the same thing hunting West Virginia, only it is not as bad there.
