Mark Koehn from Upsala, Minn., dropped by Jefferson on Monday evening on his way to High Point Island, Texas. Mark is driving his father’s 1940 Farmall M tractor from the Canadian border to the Gulf to raise money for Future Farmers of America Alumni organizations. He rides at about 16mph and makes about 150 miles per day. You can follow his journey, and donate, to the cause via Facebook or the QR code above.
