We have flown the Gordon strain for over a decade. They are an American family that has been proven over the race course--they are incredibly tough. On days when nothing else comes, you can count on the Gordons. We count on them, especially on long races 400 miles and farther. We have added some HVR and Jan Arden genes to our long-distance program. It is amazing to have a bird arrive and win after flying 500 or 600 miles. In our opinion, it is one of Mother Nature's miracles!
