I don't know whether anything has changed since 1994. Back then, I had to change all my US$ into the Burmese kyat currency. Apparently the currency given out to tourists is different from what the locals are using! It was compulsory for Foreign Independent Travelers (FITs) to exchange a minimum of US $300. Don't panic. The Central Bank of Myanmar issues Foreign Exchange Certificates (FECs) in Dollar Units. For more details, perhaps you may like to check with your local Myanmar Embassy. Also, please remember to declare ALL your possessions in one of the many forms you're supposed to fill up! Because if you don't or have inadvertently forgotten to declare say... your camera... don't be surprised if you get taxed for that camera when you're leaving Yangon.
Footnote (May 2002): I have finally checked on the latest policy about bringing money in to the country. Everybody needs to apply for a Visa, which comes in various category. Getting a tourist visa, valid for a stay of up to 28 days, in one of the Myanmar embassies is a very straightforward procedure. You'll only need to fill in THREE forms, attach a passport-size photograph to each one of those and pay the visa fee (which amounts to approx. US$20). Visas can also be extended up to 30 days at an office of the Department of Immigration and Manpower. This process requires FIVE photographs + cost of visa fee (which costs slightly more than US$20).
Visas are also available upon arrival at Yangon International Airport. However, you can only qualify for this category IF you arrange it through a tour operator/ sign up for tour package.
I saw many locals using an umbrella to stay out of the high heat of the afternoon sun. If you are fair skinned beware that it is scorching hot in March! This shot is taken in front of Sule Paya.
I saw alot of Fans in this shape being used by people. Especially Monks but they would have different colors. And I think theirs were made out of cloth or silk.
