Thoroughbred owner and breeder Gary Biszantz has put half of his Lexington, Ky., property, Cobra Farm, on the market. But he intends to stay in Thoroughbred racing, according to realtor Arnold Kirkpatrick.\r\nTwo portions of Cobra Farm totaling about 196 acres are listed with Kirkpatrick and priced at $45,000 per acre. One tract includes the foaling barn where 1977 Triple Crown winner Seattle Slew was foaled when the property was Ben Castleman&rsquo;s White Horse Acres and where 1993 juvenile champion Dehere was foaled when Robert Brennan owned the farm and called it Due Process Farm.\r\nAlso offered are five other barns totaling 74 stalls, the farm&rsquo;s office, manager&rsquo;s house, and a guest cottage.\r\n&ldquo;Gary is not getting out of the horse business in any way, shape, or form,&rdquo; Kirkpatrick said. &ldquo;His true love, as far as the horse business is concerned, is breeding and racing homebreds. So he&rsquo;s going to do that. He&rsquo;s going to cut back on his operation and just breed his own horses to race for his own self and, like everybody else, maybe sell one or two every so often.&rdquo;\r\nCobra Farm, named after the golf club manufacturing company Biszantz co-founded, is bordered by Iron Works and Newtown Pikes north of Lexington. Biszantz, 75, purchased the core property from Brennan in 1995 and expanded it to 345 acres. Among the graded winners he has campaigned alone or in partnership are Old Trieste, Cobra King, and Admise, among others.
