WASHINGTON, DC - JANUARY 31: Several hundred volunteers listen during the orientation to a Point-in-Time (PIT) count walk with local homeless advocates to find and identify the number of homeless Americans on the street, including veterans, as part of an effort to end veterans homelessness by the end of 2015, at National City Christian Church in Washington D.C., January 31, 2013. The PIT count is an exercise that the U.S. Department of Housing and Urban Development has required of jurisdictions nationwide in order to receive federal grant money aimed at reducing homelessness.
