The dominate buck isn't always the buck with the largest rack or the oldest buck in the area but the 8 does appear to be the older of the 2 . Couple of nice bucks , good luck !!!
Ok. I got it to play. I think you are right and he is the dominant buck. Like JLS said, the Dominant buck doesn't always have the bigger rack. Those are some Great Bucks man! I hope you tag one of them!
