I’m back on the Pentagon bus for a couple weeks, cruising into Crystal City on the early side, hopping off before my stop, hoofing it through south Arlington before 7 a.m. It’s pleasantly cool this morning, and already a hustle-bustle on the streets.

Joggers, yoga-goers with mats slung across their backs, the caffeine-starved piling in to Starbucks and, of course, the dog walkers.

I notice a new restaurant, a crane where there wasn’t one before, an empty lot with an abandoned grocery cart. The smell of croissants or French bread baking. Traffic noise, especially on East-West Highway.

It’s a 15-minute stroll to the office from the first bus stop, and I listen to the same piece all the way, Sleepers Awake, Bach’s cantata, times five. By the time I got here, I was floating.
