The North Maine Fire Protection District received a section of steel from the World Trade Center wreckage and unveiled it on Sunday at a memorial service commemorating the 10th anniversary of the worst terrorist attacks to date on US soil. The artifact was incorporated into an existing 9/11 memorial in the Ridgewood Cemetery on Milwaukee Avenue.
