Look it is a real simple equation.
Does not matter if you are in the north, south, east or west deer need more than anything to get big is age. The UP can and has produced so nice bucks. By no means is it farm country. Yes deer get bigger in Midwest, but it is all relative to where you live.
We can not compare size from state to state IMO, but age we can

Funny the states people were talking about in Atlas thread all do one thing very well
