You'll forgive me if I post another photo of the rain. Personally, it's something I can't get enough and just think it's kinda cool.
Taking photos in the rain is akin to low light photography, the weather has a way of creating a mood. In Europe, it's enhanced by the architecture of the old streets.
This was taken on a rainy October day in Malaga when I got soaked to the bone. About a year or two prior I did the same thing in Solerno. Back then I bought an umbrella from a vendor who magically appeared as soon as the rain started. I paid too much for the umbrella and then lost it on a bus. I've since given up on umbrellas when taking photos. Besides, it's not really feasible to hold an umbrella and take a picture, unless you have three arms.
