Great buck-congrats! Looks like you are doing things right to get older bucks. One thing I highly recommend is to make a sanctuary area where the old bucks feel safe. Never ever go into it even in off season-should be at least several acres with really thick/nasty cover-do this and the big boys(3.5 & older) will stay around way more! Jim Remember stay out it period-don't even go in looking for sheds in the spring. Only exception would be trailing a wounded deer. Good Luck!
