i was in canyon state park with though veterans, wounded warriors that were going on a bicycle ride. biking with president bush, who was literally standing on a hill looking over them, encouraging them on and down with them, helping amputees up the hill and he was clearly part of them, it was a deeply stirring experience, eric, about mind over matter, about veterans who have been wounded, trying to get back to society, to regain the new normal, overcoming post-traumatic stress, amputations, and traumatic brain injuries, and, to be part of that, was so moving, to me, and, it is clearly an inspiration and is helping the veterans recover, is the main thing. >> eric: it shows caring and dedication, by the former president, that he is out there on his bike and we know how he loves riding his bike and being involved in this issue and it's an issue that really should be near and dear not just to the president's heart, but, to all of us, honoring u.s. military veterans, injured in iraq and afghanistan. let's look, as dr. siegel goes along for the ride. >> here we go! >> heros in the wars. se
