Husband and wife team Craig and Michelle Pinto of Herndon tell guests at the Station 21 open house in Fair Oaks about the Community Emergency Response Team, which trains Fairfax County residents how to respond to all types of emergencies — from pandemics, terrorist attacks, natural disasters to a zombie apocalypse. Training is free and the next course starts Nov. 6. Learn to respond safely to emergencies of all types at www.fairfaxcountycert.org.
