I think somebody here is full of prune juice.

You can't tell if a deer is a buck or a doe by just the tracks.

Where I live in Pennsylvania, most bucks never gets past two years of age, because every rifle season, 90% of all the mature deer were shot.
When antler restrictions came along and when some people actually started to follow the rules of antler restrictions - the deer grew to a older age.

The deer in the picture was not a mature buck, he should have left it go another year and then it would have been more mature. I would guess the age of that deer to be around 2 1/2 years old MAX.

One thing my dad passed on to me when I was younger was in deep snow, often times a buck will drag his toes when he runs / walks.
If you see the sprag marks in the snow - there is a 50/50 chance that it was made by a buck. But there is no guarantee's that even if you find the track that the deer is going to have a trophy rack on it.
