You living in the "humidity capital" of the world in the DC area know all there is to know about humidity! 😮 😮
As bad as humidity can be here in Toronto, we visited DC a number of years ago and I truly thought we were going to have to spend the entire weekend in the pool! Then, when we were leaving, our flight was delayed by massive thunderstorms. After two aborts, our Air Canada RJ pilot got permission to leave, and we took off, straight up! Looking out the window, I said to my wife, "We have never been quite this high." when the Captain came on and said "We got over the storm, we are at 50,000 feet, and are now starting our descent into Toronto!" 😮😮
