Taylor Morris recently returned to his hometown of Cedar Falls, Iowa for the first time since May 3, when he stepped on an IED in Afghanistan that blew off all his limbs; he is one of only five surviving quadruple amputees. Now he is back for long hard rehab at Walter Reed, where his girlfriend Danielle has not left his side since he was injured. Morris is 23. Over 2.4 million Americans have served in Iraq and Afghanistan. Today, it goes on. How many more will there be? His story, wrenching photos, Facebook, much more.
