Lincoln Park 9-11 Statue

My wife and I run past this statue at the corner of Ackerman Blvd and Lincoln Park Blvd in Kettering all the time on our four mile runs.  But until this last Sunday we've only seen the side shown in the picture on the left below, unaware that its true meaning was carved into its opposite side, the picture on the right.  Sometimes it pays to turn around.
