This Feb. 15, 2013 photo shows the grave site of Capt. Peter Linnerooth at Fort Snelling National Cemetery in Minneapolis. Linnerooth's friend, Brock McNabb mulled over how to leave a legacy for his friend's kids - a memorial that would give them peace and make them proud. But he was limited to 30 characters for the message on Pete's headstone. How do you honor a life in a handful of words? McNabb then remembered something Linnerooth had once told him: &quot;Maybe we're all meant for just one great deed and we're done.&quot; (AP Photo/Jim Mone)
