I know, it sound like a stupid question. You wear a rain jacket when it rains. How simple can that be?
Well, I do not think it is that simple. At a temperature, and I am sure that temperature is different for everyone, a rain jacket is not needed for a rain.
Today it was warm, or in the high 70s or low 80s. I did not take my rain jacket even with a major threat of rain. I find a rain jacket uncomfortable above a certain temperature even is a fairly hard rain.
At what temperature do you leave the jacket at home, or do you?
