Yes much bigger in the UP than lower Michigan on average. I have trapped and hunted them in both UP and lower Michigan since a kid and maybe 1 30+ lb out of a 100 Coon
I think my father had more 30+ Raccoon than any man I ever new. I remember as kid he left more raccoons in trees and let more go in traps and we always had more big ones then my brother and I wanted skin. The pic was a common night in the UP in the 90's
Back in NAFA days, a 5xl coon was one that a solidly at or over 38 inches from nose to base of tail. A 6xl would be another 3 inches in length, so at least 41 inches...?
