welcome to the group!!
i envy ans salute your trip through vietnam on bike! must have been the most maniacal journey ever! if you made it through there alive, i'm sure china will be fine for you! lol
did you start from the north or south?
i was in vietnam in september and we moved from north to south, going from hanoi, hue, nha trang and ending in saigon..
we did manage to get some scooters and ride around for a day in nha trang, that was awesome!
