Ho Chi Minh travel

I start to suspect that I do not have the luxury of going on a good vacation.
Since the trip started in Ho Chi Minh, I am having migraine; something that I do not have in the past.
What have I done so far? Drinking the Viet coffee (Yes, for once I broke the rule and drank the nice coffee) in a nice local coffee house; with a novel on hand as well.
Oh, I have did the Cu Chi Tunnel as well..... Mmmm.... just a dark narrow tunnel lor.
Of course it does not mean much to me as compared to the war days.....
Eating beef pho is the best :-) and I just spend 50 buck on a small painting. oops...
