On our second day in Hanoi we saw the ancient art of water puppetry, as well as more museums and markets. Then we took a night train north to Sapa where we have been hiking thru stunningly beautiful terraced hills to visit hill tribe villages (Hmong and Dzao).

The roads in Hanoi certainly look busy. The terraced hills are fascinating. Looks like a lot of hard work went into the creation of the terrace (and I suspect it was manual labor vs machines).
