I wont shoot a fawn, mostly because I worry about accidentally taking a button buck. In NY we get a doe tag and an either sex tag and generally the first animal to give me a good, ethical shot, gets the blades. It puts meat in the freezer and takes some of the pressure off, makes it easier to enjoy the rest of the season knowing I already have one down. I don't begrudge anyone who only wants to shoot 3.5 year old and up bucks, but I personally think it takes a little bit of the joy out of the whole experience.
