Join the Greater Grass Valley Chamber, City of Grass Valley, American Legion Post 130, Grass Valley Fire Department, Grass Valley Police Department, and Nevada County First Responders on the Mill Street Plaza near the Del Oro Theater to commemorate the lives of those who died in the 2001 terrorist attacks on the World Trade Center in New York City and the Pentagon in Virginia and those who perished when the hijacked United Airlines Flight 93 crashed in Pennsylvania, and those who died attempting to rescue people trapped by the attacks. We Will Never Forget
