I stayed in these bamboo bungalows with Teak leaf roofs, while I was in Pai. Pai was a very layed back small town with more Farang (Thai for westerner) than anywhere else I've been. It rained for almost three straight days and the river rose dramatically. The bridge is made of bamboo and had a bit of a sway when you walked across. The river is only about two feet deep but has a very strong current and the dirty water makes it appear more dangerous than it was.
