I know I promised photos on the inside of Bangkok taxis, but it's Songkran Festival in Thailand, and it's impossible to ignore what's going on outside. Songkran is the Thai New Year which is celebrated every year at this time. Traditionally, it involves a ritual of gently pouring water over your elder relative's hands. But, today the festival has turned into a 3 day all-out frenzy of spraying and splashing water in the streets.
If you want to stay dry, this is a good time to ride in a car taxi (if you can find one that's available). Otherwise, put on your Hawaiian shirt, grab a water bucket or a Super Soaker, and get ready for some wet and wild fun!
