Do you:
Stay inside and try to find an indoor photography project?
OR
Brave the weather, protect your camera (if it's not waterproof), and head out to find shots that nobody else will get because they think that rain means that you can't go out and shoot?
So, which are you more likely to do, and do you have any rainy day photos to share with us? Whether they're actual rainy days or photos that you've decided to do because of the rainy weather, tell us all about it.
