Ginkgo trees are developmental throwbacks, with the entire length of their angular limbs festooned with fan-shaped leaves. The other trees, more modern, yet somehow more old-fashioned looking. push their leaves to the ends of their branches, like hands, groping the sky for more light.
The ginkgoes have already turned, this fall, and their brilliant yellow leaves litter the sidewalks and clog the gutters. The other trees still hold some of their green, turning more slowly, reluctant to acknowledge the coming cold.
