It will always be the first thing I think of on Sept. 11.
It remains one of the most beautiful blue September skies I've ever seen.
A couple of things.
First, I find it hard to believe it's been 16 years since we all first looked on in horror as a plume of gray smoke altered that blue sky - and our lives - forever.
And I now have a second blue sky connected to that day that continues to haunt me.
I explain it in my weekly Letter From the Editor.
