Going to backpack solo in Vietnam this August from HCMC to Hanoi (gonna take 3-4 weeks). Well, did my homework a bit on the places, food, culture and all. Relied on Lonely Planet for that too but I figure that personal experience shared by fellow forum friends would be great...
My questions to Vietnamese/those familiar with Vietnam: Any personal recommendation/advice and friendly tips? Must-go, must-see, must-do list? Anything to watch out for?
