But there have been reasons to celebrate, and the change of seasons brings pleasures forgotten over the past year. Colors shift, landscapes transform, and plants somehow remember to prepare for winter. The shifting sun brings that distinctive fall light. Mosquitoes go wherever they go, thank heavens. Big squashes and apples appear at the farmer's market tables (replacing those luscious August peaches, alas). Fall is a beautiful season, and we anticipate it with gratitude for nature's cycles.
