I'll never make fun of you "be prepared" and "take precautions" types again. I have learned my lesson. While in Paris on business, continually watching out for meteorites and concealed-carry guys on the verge of a nervous breakdown, little did I know my true enemy was a volcano.
Ever on the lookout for innovative solutions, my colleagues and I made our escape in a borrowed car, slipped through the longest tunnel in the world (I think) and made it back to sunny Italia.
The lesson: one can never be too prepared.
