Jeff, my son killed a doe in firearm season about 4 years ago that was aged at 7.5 years old. They about fell over at the FWA check in station when they did a teeth check. Her teeth were all but gone and they made the coment that she may even be older than 7.5.They said they had not had one checked in that old in a long time. She was very long, and gray around the face and forehead. I have a pic somewhere i may post latter. To us it was a trophy, we dont see them that old in our area and this one was actually an easy one, she just casually strolled out of a thicket into his sights.
