Who sits in the sun when the heat index is above one hundred degrees? I could see those sun-struck people from my slightly more comfortable seat on the opposite side of the Nationals' stadium. They were a blur of yellow T shirts, made brighter by the last hour of unrelenting sunshine. Melting in my own seat, I climbed to the upper deck. Ah, a breeze, and a better view of a hazy sunset. The friends in yellow T shirts were clapping and waving, having a fine time. They may have been stuck in the hottest seats, but they were all in it together.
