I went on an 'urban hike' today, wandering around much more of San Francisco than I'd planned, going up and down several hills - I took my camera, and didn't capture anything brilliant, but I got an OK shot of downtown SF from Bernal Park:
A beautiful snow is falling right now. The flakes are light and silent and accumulate almost imperceptibly. It is the kind of snow you only get when it is cold and calm; they are the six-sided, reflective snowflakes that cover Christmas decorations. I went out on my deck and admired them with a flashlight. Many of them fell from the sky to the railing of my deck still perfect, with all six points intact, myriad shapes and sizes. Little feathery wisps, hexagonal mirrors, miniature Stars of David. The ground sparkles as I walk.
