Great video! I have seen several really good videos of buck fights. The best one was an old VHS tape one taken in Dimmitt County in the early 90's. It lasted over 45 minutes with 10 or more other bucks running in or around the fight. One buck flipped the other one into the air, over and through cactus. The fought across a road and back. Both were really good bucks and a very mature 10 point with a larger drop was brought in by the fighting. The hunter shooting the video did even see the droptine buck till he viewed the video at camp later. He said he would have shot that buck, but never saw him again.
I was able to get pics of a buck fight this year in November. Only last about 1:20 seconds but got a lot of good pics.
Ranch, I've seen that video that you're talking about. Awesome South Texas fight, been fortunate enough to see some good South Texas sparring in my time; always fun to watch.
