On Friday it was miserable in Atlanta. 90, humid, and the sun was blazing hot. By 10 am it was too hot to be outside. We got on a plane and flew to Dayton where there were having a heatwave. It was 94 out and the rental car lady warned us it was too hot to walk to our car so we should wait for the shuttle. We stepped outside -- it was LOVELY. Somehow, even though it was 4 degrees warmer, it felt about 10 degrees cooler than what we had left. How does that work?
