There were torrential rains in Hue the entire time were there (7 & 8 October) that left the streets around our hotel flooded. Therefore we did no touring there and caught up on sleep. This is unfortunate because Hue is the site of the original capitol of Vietnam and the Citidel, although mostly destroyed in 1968, is one of the prime historical and architectural sites in Vietnam. We will revisit Hue again sometime to catch up. We are now on to Hoi An south of Danang.
We travel by "backpacker bus" which is not as bad as it might sound. These are modern air-conditioned comfortable buses that operate on an "open-tour" basis between Hanoi and Ho Chi Minh City. You buy a ticket book for the entire route by segment and get on and off at each destination. US$20 each for the entire route. Just takes time.
