Did it on my fathers old farm for 2 years before AR's (he's in PA). The last season he was there in 03 after several years, we were seeing many good sized bucks. Much more than the years before. Our rule was 8 points or wider than it's ears to shoot. You had to use common sense to judge whether it was at least a 2 1/2 year old or better basically.....most of the ones we actually shot were 3 1/2 though.
