The advantage of a second language on your travels

Do you love traveling as much as me? Well, once you realize that so much of the world either speaks no English, or the quality they speak is so bad you can't understand it anyway you should think of learning another language.

As the third most common language in the world and a neighboring language to the United States, Spanish is the obvious choice. OK, it's no good if you're visiting Rome for instance, but much of the Caribbean, Mexico and South America speaks Spanish.
