The crisp cool air, swirling around you, wrapped in a coat and a scarf. The leaves as they turn from green to yellow to orange to red to brown, soaring through the air and collecting in a multi-colored leaf orgy on the ground. Bonfires and s'mores, the smoke twisting and rising into the star-lit night. Apple picking in the orchards, the sweet juices dribbling down your chin. The beginning of the winter holidays, the bittersweet ending of summer.
