Just found out that Kirby is now riding for Ronix, congrats man! I grew up riding with this kid at Lake of the Ozarks, we used to compete together in INT, since then he has progressed so much. It is so fun to watch him ride. He also started a wakeboarding school at Lake of the Ozarks. I am looking forward to seeing him continue to progress!
I found this video on Alliance a while back, if you haven't seen it, you should check it out.
