Here are some sketches inspired by Thailand, ie, Phuket and Bangkok.
Taking the river taxi in Bangkok is a particularly local way to travel. It's cheap, and more efficient than by the road. Although I have worries about boarding and disembarking from the boat due to the gap between the boat and the docks (I've an irrational fear of falling into the muddied waters of Chao Praya River), I did enjoy the boat rides. Do give the river taxis a try if you were to visit Bangkok.
