I tend to spend the fall looking up at the trees to see the autumn colors. I particularly like the early fall as the leaves form a sort of autumnal spectrum of colors, ranging from deep burgundy in the upper most branches of a tree through flaming reds and oranges, to yellows, and on to greens in the lowest branches. The maples put on a particularly lovely display.
But I also look down for the remnants of those autumnal spectra. The other morning after a gentle drizzle, two leaves lay on some paving stones not far from the maple where they had until recently hung.
