Amazing Race 10 in Vietnam this past summer

Last week I had a chance to catch part of Amazing Race 10 in Vietnam - Hanoi, and Ha Long Bay. I just want to catch a little glimpse of the cities that I got to visit 2 years ago. I'm looking forward to another visit soon, may be within the next year or 2.
But in the meantime, I'll just watch this video:
