When I look at the number of big bucks coming out of WI...I try to come up with the differences between two neighboring states. WI has no APR zone, MN has a tiny area of the state with APRs. WI winters are similar to MN winters for much of each state. Growing seasons/frost free days are similar. Rainfalls aren't much different. Each state has a variety of soil types. Why does WI produce far more large antlered bucks?
My answer is simple...the WI herd is much larger. More deer...more chances that more bucks live long enough to become large antlered males.
