Today I got a unique opportunity to explore a small piece of Thailand’s rural heartland aboard a traditional teak rice barge, the Thanatharee, sailing on the Chao Phraya out of Ayuttaya – the ancient Thai capital an hour and a half north of Bangkok – and into the rich agricultural central plains. Comfortably repurposed it could not be beaten as the perfect place for a long, cool drink and a languorous lunch while watching the world drift gently by. That is, until the weather abruptly – and radically – changed.
