Yesterday, I was a walker in the city, not the suburbs. I began at 18th and L, deep in the business district. But that’s not where I stayed.

The Mall was my destination, heading toward the Capitol and my former walking route, site of numerous lunchtime strolls.

The monuments were there, glinting in a warm winter sun. The White House, the Washington Monument, the Smithsonian’s Arts and Industries building.

What was missing, what always seems to be missing these days, was the people. Empty thoroughfares make good straightaways, but what I would give if this scene were clogged with tourists and pickup soccer games and pale office workers out for a noontime jog.
