When on a long tour I plan my rest days based on the weather. If it is going to rain then I rest. When I am riding and it decides to rain then I get wet even though I have a rain suit that is impervious to water. In fact I have never put my rain pants on when riding, just the jacket. I don't really mind riding in the rain if it is not cold, but when it is raining hard I am convinced that drivers of the vehicles on the road do not see me. Just my opinion, and I always have the option not to ride. Touring is not the same as commuting to your job which is mandatory even on a rainy day.
