As he often did while crossing Commonwealth Avenue, Kush thought of how the Mall runs about a mile in length, half the length of that former fetid tidal flat. It seemed that hardly anyone cared about that fact anymore.

Nearly a mile is almost as long as seven Eiffel Towers laid end to end, he thought. 

Or maybe six. Six, if you could position the towers with the tip suspended in the air, instead of just lying flat like so many rubber doorstops.

For example, you could attach them base to base and tip to tip.

Attach them base to base. He inwardly smiled with satisfaction at the thought. Even the simple bolts that preceded modern-day rivets could accomplish that. Especially if you added metal cable, which already existed when the Eiffel Tower was built.

He made a mental note: Talk to Steve Blanchard.
