We have had that rule here in NJ for a few years now and i personally like it alot. THat along with the 3 points on one side rule has made our hunting alot better. I personally try to take ATLEAST one doe for every buck that i take and make anyone that hunts my property do the same. Taking does makes the bucks bigger and it also makes them more active looking for the does that are left. Only positives in my book.
Now for the negatives, which arent really negatives in my book, but ways around the system. Most of the check in stations around here dont do much other than look at the deer real quick and pat you on the back. That being said i know alot of people refuse to shoot does around here saying it will hurt the hunting, and to get around the rule they simple pick up the first road kill doe that they see or simply dont check their deer. I dont agree with it at all, but it happens.
