Wildlife Game Masters

With the PA gun season winding down, I know there are a few tags out there still not filled.  Some because you just haven't had a good opportunity at a buck, some because you have been waiting for the right buck.  At what point do your standards change and you go into "kill mode" so to speak or do you?  Do you hold out to the very end sticking to your standards when the fact is the deer you are looking for may no longer be in your hunting area or may have already been tagged by another hunter or do you lessen your standards just to fill your tag?
