At 8 a.m. on Sunday, a man will embark on a 42-day walk from the Pentagon to Shanksville, Pennsylvania to the World Trade Center in New York City to honor the first responders who risked their lives on Sept. 11, 2001.
The journey is personal for Frank Siller, who is traversing six states and more than 500 miles in memory of his brother, New York firefighter Stephen Siller, who died responding to the terrorist attack. The surviving Siller plans to arrive in Manhattan on Sept. 11.
