Three-minute interview

11 year-old Zach Bonner arrived at the White House on Thursday after walking 1,225 miles over the course of 20 months from his home in Tampa, Fla., to raise awareness about homeless children. A movie about him and his community service foundation, Little Red Wagon, is scheduled to open in 2010.

How long did the walk take?

I walked from Tampa to Tallahassee in November of 2007 and Tallahassee to Atlanta from October 17 to November 17 of 2008. I left Atlanta on May 11 and got to D.C. on July 9. I walked between 11 and 13 hours a day.
