Travel Vietnam for less than 15,000 dong a day. You get a two stroke motorbike, a comfortable double bed strapped to your back grill, and last but not least - all the open air you can handle. Your travel insurance will not cover this however, so if you break your neck navigating death defying traffic in Saigon, don't expect to get paid for it. It is however a relatively safe mode of transport around Vietnam. Close to 85 percent of motorists live long enough to return the bikes. So if you are fairly confident on the road, and value travelling more than your own life, this is for you. Venders are absolutely everywhere, but generally those with only one leg will give you the best rate.
Happy motoring!!!
