for me, Southern tier is my primary hunt...

Southern tier deer are generally smaller than the northern counterparts in wieght (as far as ive noticed) but are generally much bigger in mass and rack size where i hunt. a good northern tier deer (buck) for me is anything with horns, southern tier it is a big 6 atleast. I think that the sparseness of deer in N Tier play's a major role too...(harsh winters)
