Ray Kozak is trying to lasso a Guinness world record.The Warren County cowboy successfully completed a feat he believes will put him back in the record book in the category of largest lasso. Kozak has twirled a lasso that was 115 feet, 1 inch in length at his farm off Old Shelbyville Road.If accepted by Guinness officials, it will beat the current world record of 107 feet held by a Chicago resident.“People ask me how I do it and there’s really no trick to it. It just takes practice,” said Kozak, 55.
