On Friday I had reason to visit Georgetown’s main campus — or, rather, an office building 20 minutes away from it. Though I work at Georgetown’s law school, I seldom visit the rest of the campus, what’s fondly called the Hilltop.

It’s a beautiful spot, perched above the Potomac and set apart from the rest of the city. But it’s not easy to reach by Metro.  My favorite way to go, though most would say the most arduous, is to get off in Virgina at the Roslyn Station, wend my way through downtown Arlington and then stroll across the Key Bridge.

Friday’s weather was brisk. I wore a jacket and scarf. I considered gloves. But none of this mattered once I started across the span. There are the spires of Healy Hall ahead, and beside the campus the narrow, treed lanes of a much older city. Below is the Potomac, and, if you’re lucky, a crew team skimming across it. The bridge is clogged with trucks and cars and bikes. All is movement and brightness and wind.

And once in the District, there is an impossibly steep hill to climb. They don’t call it the Hilltop for nothing. Motion, sunshine, new vistas — my heart was lighter than it had been in days. And all because I walked Key Bridge.
