Mortenson, if that buck was in my neck of the woods I would guess 4.5+ (emphasis on the "+"), and not just talking horns... face looks grizzled / older, and really square bodied with deep brisket for 3.5. Regardless, heck of a buck. Hope others can help you pin down a more accurate / confident age on him. Again, if in my neck of the woods I would be thinking of harvesting him in fear that future years might actually see him declining.
