Next week (Wed. April 25th) my office along with the National Fallen Firefighters Foundation (NFFF) is doing a memorial stair climb at the Washington Hilton in Dupont (1919 Connecticut Ave NW). Participants pay a $25 fee, climb 110 flights of stairs in memory of a firefighter lost on 9/11. NFFF gets the proceeds. For more information on the Foundation you can visit firehero.org.
