Yesterday, I took an impromptu walk down the Mount Vernon Trail, starting at Gravelly Point. Planes were swooping in low to land, so low that the wind from their passing ruffled the leaves of trees in their path. An enthusiastic group of plane-spotters lined up at the end of the park, practically on the runway, to wave and cheer as the 737s soared above them.

The magic of the walk was in the mingling of the low-tech — the quiet lap of river water against the shore — with the high — the roar of jet engines making their final approach to National.

And then there was the beauty of the path and the District viewed at three miles per hour. The red maples still flaming, a graceful weeping willow, geese sluicing into river water before landing in a puddle under the I-395 overpass.

I hated to leave the scene: the Washington Monument rising ethereal on the other bank, the graceful arch of the Memorial Bridge, and, in the distance, the spires of Georgetown’s Healy Hall. It’s my town, if I want — and walk — it to be.
