There is a thrum and a life on the streets of a Thai or Lao city. Of those I visited - Chiang Mai and Chiang Rai in Thailand; Vientiane in Lao (Luang Prabang doesn't really count - it's too sleepy to have anything remotely close to "thrum" on its quaint and unhurried streets) - the bustle is similar. Colorful tuk tuks transporting tourists, locals, monks... locals pedaling bicycles... motorcycles whizzing by, laden with people, babies, animals and the day's shopping... pushcarts full of everything from garbage to produce for sale.
But at the end of the day, beneath any apparent hustle and bustle, it's still "Same Same" in this part of the world: nowhere to be and no rush to get there. It's a nice pace for a change!
