A raindrop that falls into the headwaters of the Mississippi River in Minnesota will reach the Gulf of Mexico 90 days later. When I learned that, my world was sent spinning in a new direction. I knew in that instant that I would make a 90-day road trip, following the entire course of the Mississippi River, while keeping pace with an imaginary raindrop that I would call "Serendipity." From that moment on, this adventure has created itself in ways that often seem magical. People offered lodging in places that let me slide body and soul into the local culture. There was a fisherman's cabin, a trendy downtown loft, a tugboat converted to a B&B, a plantation mansion, a sharecropper's cabin - and once, an entire 30-room manor! The Mississippi is one of America's greatest treasures. It is embedded in our history, our present and our identity as a nation. Along its roughly 2,400 mile journey, it is transformed from a tiny creek into an immense force of nature. It passes through dramatic changes in geography, climate, culture, lifestyles and accents. -- Adapted from dust jacket.
