For a walk break yesterday I turned left, strolled south down Crystal Drive. The lunchtime bustle buoyed me; I was ready to explore.

It’s a neighborhood of hotels, restaurants and fancy office buildings connected by glossy indoor passageways — not my style, but handy in the rain.

Beyond all of this, I’m convinced, lie real streets with real people picking up dry cleaning, dragging reluctant toddlers, walking the dog. But to find them I first need to discover the connector routes, the roads that will take me under the busy highways that honeycomb the area.

There aren’t many of them. Crystal City is almost an island. But all I need is one escape route. The maps are open. The shoes are new.
