Pretty neat stuff! I've seen bucks spar and get a little rowdy before, but never seen two big ones lock up and go full-on like that. That must have been a sight. I did have a bruiser come by me once, on the trail of a hot doe with a small 6 point in tow. The big guy suddenly stopped spun around with the hair bristled on his neck, and gave him a loud snort-wheeze. The little guy didn't want any part of that and took off like a scalded cat. First time I had experienced a snort- wheeze.
Go get him Jon! Or send him over to my part of Illinois.
