When you buy something, you usually get a free pen, or T-shirt. But when when Dan McAllen bought a motorbike in Ho Chi Minh City, Vietnam, he got a free duck. Dan decided to keep the duck and named him “Rab.” Along with his friends, Dan planned to ride 1,000 miles across Vietnam on the Top Gear route, and Rab was along for the entire ride. Sitting in a crate strapped to the back of a motorbike, the duck journeyed across Vietnam with the travelers until they set him free into a Hanoi lake. Here are some photos from their wild feathered adventures.
