Running in the fall is best. I love those evenings when it would be just a bit cool to eat dinner on the patio without a light jacket, but running is perfectly comfortable. Yesterday was one of those days--the high was 70 and it had cooled into the 60s by the time I went for my run. The sun was moving toward the horizon, casting long shadows. I had to laugh at my shadow at one point. The shadow of my legs stretched out for about five feet on the pavement while the shadow of my torso was only a foot or so. I did a 30 minute run to the nearest train station and shared the road with a motley crew of bikers. Sometimes, I still don't believe I'm living in Korea. The run itself was invigorating, fun, and I'm so thankful for these fall days, enjoyable to the last drop of sunlight.
