At an age when many children are still mastering the art of walking, Matthew Dedden was riding a horse. Dedden, 13, has been riding since he was 2 and those years in the saddle paid off last month when he became the National Cutting Horse Association Junior World Champion. "That was my goal at the beginning of the year and it took a lot of work, but I got there," Matthew said. He is believed to be the first NCHA world champion at any level from Kentucky.
