I would have to disagree with Mustafa. Vietnam is a beautiful country and the people are so friendly and curious about Americans. Yosemite is beautiful too. The food is amazing. Saigon is very modern like most big cities else where. If you're in the area, Cambodia is awesome too. Ankor Wat and the other temples are beautiful. Laos right now seems to be untouched by development and worth visiting too. Travel with your camera and follow your curiosity.
