If you were as informed as I am you would know what areas are producing the most big buck and you would know it is the areas with the highest densities where bucks should be subject to the most stress according to your theories.
If you had a logical thought process you would have realized these bucks have access to a lot better nutrition. Also, there's a lot of hiding places in the suburbs...we have a lot of bucks reaching maturity. Not saying north central dosent, but they certainly have less than down here.
