Today was the 13th anniversary of the 9/11 terrorist attacks on the World Trade Center and Pentagon in 2001. In mid-afternoon, accompanied by the revving of motorcycle engines and honking car horns, a parade of motorcycles—many adorned with the U.S. flag, motored down Seal Beach Main Street. Visitors, merchants and employees stopped what they were doing to take pictures and pay their respects to the lives lost that day in 2011.
