traveling the world. What makes them special is that they actually did it; what's more, they did it on
bicycles.
     At 18, Vicky read the famous Cycling Diary of Hu Rong-hua and was   1   to take a bike tour of
southern China by herself. In 1991, while riding along the island's east coast, she met a Japanese   2  ,

village, where Vicky and Pinky farmed, cooked, and danced with the locals.
