Two gatherings of first responders in Bryan County Sunday morning marked the 15th anniversary of the Sept. 11, 2001, terrorist attacks. A bell was rung at the Veterans Memorial in J.F. Gregory Park as Richmond Hill Fire Chief Ralph Catlett read off the events of that day, marking a tradition that dates back 200 years at firefighter funerals known as “Last Alarm.” The tradition recalls a time when a bell was used to call firefighters to action and rung again to mark the end of a call.
