Once famed for their horsemanship, the only New Jersey Cossack to own a horse now is Sienczenko, who got a good deal on Ruler, his retired racehorse.. I am a cossack living in new jersey.. I own a horse... and my pictures of being on horseback are at the New Kuban Historical Museum in Buena NJ. I am constantly learning horsmanship. My Horse is a 20 plus year old gelding named Kody.. nicked named KodyKhan...I joust and shoot arrows from his back like my anscestors. I am a Miroschnitschenko. Grandson of Vasily. I am a Cossack.
