The building above is what remains of Eola, a small farm community just west of Naperville. It is now part of Aurora, Illinois. And, the post office is no more. In fact, if you look closely you'll see a FOR SALE sign in the window.
I remember when there was a sign on the building that said: EOLA
Instead, today, we have an eight lane divided highway which rumbles just east of the building as drivers pass over the Burlington railroad tracks, unaware of the passing of history.
I imagine that in the "olden" days this post office was the hub of the small town. The train probably stopped nearby dropping off express mail, or freight, or even passengers coming from downtown Chicago.
And, just a few blocks north is an elegant townhouse community and I suspect those inhabitants never drive down here as the road dead ends. Another time, another century.
