You were using the ears and eyesas reference to judge mature whitetails , I have read in one of those hunting books that when they'er born , there ears and eyes will be the same size as to when they get older.
So even if this were true (which I dont believe the ears bit and I am skeptical about the eyes) would those not be accurate refrence point? An inch and a half is still and inch and a half right? Seven inches will still be seven inches......
