If it dosen't have a drivers license just ask it's mama!!
Seriously, I've always heard the teeth is a good way to age a deer.
As for as the people in other forums goor any where for that matter, any body that chews you out for not hunting their caliber of game is of no concern,just remember you hunt to please yourself, no one else so
shoot any legal deer you want. That's what the season is for.
