With an anterless deer tag and a deer that you could positively identify as a button buck well within archery range in front of you broadside would you let him pass because he was a button buck?
Do you honestly believe you can positively identify a button buck?
Yes and yes! I' m not gonna waste a tag on 35lbs of meat!
It' s fairly easy to distinguish a yearling (fawn) from an adult deer. I wont shoot a yearling doe either.
