Last year, I travelled through Vietnam for a few weeks. I rode plane, bus, car, boat and motorbike to discover the country. By bike was by far the most fun way to travel. I was lucky to find an Easy Rider (as they call themselves) to take me from Hoi An to Dong Hoi. He stopped in between to see some interesting places and in the end he dropped me off at the train station to catch the night train.
Traveling by bike gives you the freedom you can't experience with any other type of traveling. I had my camera on my lap, I made my shots on the go or we stopped whenever we felt like it.
