  Former U.S. Marine Cpl. Daniel Riley, 21, sits on his bed with his belongings packed for storage as he prepares for a lengthy trip that will take him as far as New Zealand on Thursday, Oct. 4, 2012 in San Diego. Learning to walk on his prosthetic legs was "like kicking a soccer ball in a swimming pool." But he didn't just learn to walk; he has learned to soar. He joined "Operation Rebound," and has graduated from competitor to mentor. (AP Photo/Lenny Ignelzi)
