I see your up from your knap sunshine
I have no doubt it helps for eating, but as HB pointed out this thread is about midwest deer having an advantage. What I am try to see is it the Midewest or river bottoms that are the key. I bet you find health deer in river bottoms of MA, PA, NY, NC, GA, MISS, etc is better than other locations on Avg.
I think it is the river bottoms more than anything. In MI you find big deer near the river bottoms. Not that deer are not big elsewhere, on averagedeer thatlive in or near river bottoms I bet tend to be bigger (Body and Antler).
