What do you do if you're on vacation and the weather is crummy? If it's pouring rain, I try to find indoor activities to do, such as museums or galleries. I find that there is almost always some sort of good museum or gallery wherever you travel. Even a cute café with local food is nice to just sit in and relax with a coffee and ponder life! If it's only sprinkling I just usually grab an umbrella and still head out and do what I would normally do - a little rain never hurt anyone, right?
