RE: how grow bigger bucks
Let them walk. Look at PA this year they are producing some nice bucks because the younger ones have made it through. They put a law into place restricting what you can shoot. so the younger bucks have got to get a few more years on them.
Here in Ohio we can only take one buck. So it forces people to wait for something better.
Indiana has some nice bucks too. But in your area I'd bet, if your not seeing bigger ones, they are being shot when they are to young. You got to let the younger ones get older or there will be no big ones.
