If I remember correctly, Robert Louise Stevenson also wrote the word mizzle in 'Travels with a Donkey in the Cevenne.' I'll look it up later to see what sort of rain he was experiencing at the time. Rain is very varied, the type I dislike is when it's very cold rain, heavy drops and very windy and when you have to walk directly into it! I experienced a different once-only type of rain in the Lakes when hiking the Cumbria Way and had reached the shore of Lake Coniston when it started. There was no wind that morning, the clouds above me became really dark and they were so low and heavy and I felt I could almost touch them. There came a point when the rain seemed to come down almost in one go, it was intense, the rain really heavy and vertical and also warm as well and it pounded on my head for more than an hour. That day for me was most unusual and I've never experienced rain like this since.
