The 20th anniversary of the September 11, 2001 attacks is less than two months away. Hard to believe. A whole generation has grown up, gone to Afghanistan, and returned home who were not born on the day of the attack. Most of these young men and women have never heard of Pat Tillman. They don’t know of his sacrifice or death. Yet when Bagram Air Force base was shut down, the USO made sure to remove his last football jersey. My heart swells.
