So has everything else that is discussed on here. In the words of Solomon, "There is nothing new under the sun." Besides, the "search function" is a joke. Good luck with that.

In warm weather I'n not sure I'd carry a rain jacket. I did a 6 day tour in April and took a bare minimum. I got caught on the first day on a 3 1/2 mile bridge over the Albemarle Sound when the bottom dropped out. No way was I stopping on a bridge in high wind, rain, and heavy traffic to put on rain gear. By the time I got to the other side I was already wet. Anyway, what I had was pretty thin cheap stuff which kept me mostly dry, in spite of it all 25 miles later in continuous rain, I was soaked and had little spare clothing. About froze to death but .. THE SHOES! I only had my bike shoes and some flip flops. My bike shoes got soaked and remained soaked until late the next day.
So even in warm weather or with premium raingear, think about your shoes. They won't dry quick.
