Old saying -- If it is not broke don't fix it. Absolutely nothing I or you have seen backs up what they did. As far as decoys are concerned, us older guys that can'walk far in the woods and need set ups in fields, need decoys most of the time/ For those that are against decoys, how is it hurting you if others use them. You should have your personal choice and not push it either way. March 15 thru April 30 worked and everyone could fit the best time to hunt in that range. Why do you care if someone in the south wants late dates or early dates, same for the north. March 15 thru April 30 covers everyone. What fits for the north may not fix for the south, so if they refuse to lay out dates by region,then lets go with dates everyone can live with.
