Community members are invited by Mid-Columbia Fire & Rescue to join emergency responders Sunday for an observance of the 15th anniversary of the Sept. 11, 2001, terrorist attacks on the East Coast. Firefighters and law enforcement officials will gather at 7 a.m. at Station One, 1400 W. Eighth Street in The Dalles, for the short program. “When 9/11 happened, the mantra became ‘Never Forget,’ and I think that was not just so that we would remember the losses of that day; it was something that we needed to cement in our minds so that we would guard against it happening again,” said Fire Chief Bob Palmer. Palmer opens the ceremony on Sept. 11 by recounting the events of 9/11, and then Chaplain Marilyn Roth will give the invocation.
