My wife and I have spent time in many states here in the USA, just about everyone has a 3-4 month period where the outdoors are difficult. Here in West Palm Beach, Florida you can almost count on a nice breeze to make you comfortable. In the shade that is!!
I do not use an overcoat. I'm always in short sleeves. Shorts and short sleeves in restaurants, and occasionally I am in customers homes, in shorts, tunning their pianos. Does it doen't get much better??
