“We walked from Pointe-Du-Hoc to Omaha Beach through wheat fields and poppy fields…and you imagine just what our guys had to go through to get up on that shore. You look up at those cliffs and you think about the rangers that had to scale those cliffs at Pointe-Du-Hoc, with the machine guns and the grenades coming down on top of them; I still don’t know how they did it.” – Dr. Troy Keyes of South Dakota, who traveled to Normandy, France to participate in the challenge.
