I traveled from Hanoi, to Hue, Nha Trang, and Ho Chi Minh City (or called Saigon - when the North Vietnamese Army (NVA) won the American war (or when the Americans pulled out), the NVA changed the name of the city to HCMC. I was told by a Vietnamese - Canadian friend to NOT call it by the 'old name' when government (communist) officials are around, they will shush you).
Lets take a deep breath.........o.k. lets head to.............Vietnam. Was glad to come in the country as it was less touristy than Thailand, but was more than happy to get out. The people who deal with the tourists (the rich ones) here are a bit edgy. People who are not in the touristy parts seem like angels. I think of the country in two parts: the locals and the ones who dealt with tourists.
o.k. Will get some of the bad things that happened off my chest. Did have a problem with men, as male tour guides would ask my name, who I was traveling with and hotel room number (foreigner = money). My dig on the communist government. Was riding moto (motorcycle) in town and was told by the police to get behind the pedestrian line as I was centered on it. The police man left his post on the corner and stood in front of me until I backed up. Luckily I didn't get a ticket. Really scared me because realized how much control the government really has in the country, over EVERYTHING!! Religious and speech freedom are restricted. (This paragraph would not be allowed!! Certain e-mails from people in my church were not opened or not answered)
On the other hand, the locals are heaps of fun and a make trip back worth it. Maybe because their government is hopeless they've developed a good sense of humor and are interested in helping foreigners in any way they can. I once got to the local bus station and dozen men helped me find the right counter, made sure I had the right ticket and got me to the right bus (none spoke English). All they asked for in return was a kiss. :) (they had a good laugh about it).
I come off a bit anti-government (communist), but when freedoms you take advantage of your whole life are taken away, it's a bit of an adjustment. If you are American, the DMZ page is worth a look.
