When we took the 2-hour Express Train to Laoluong, we passed green farmlands among small, low cliffs. "What are all those caves?" I kept asking. It looked to us like people lived in them.
Sure enough, it's common. From what we've read, it's the kind of thing this fast developing country would like to improve upon, so cave homes aren't discussed much. They may not want to brag about them, but they're wonderfully sustainable. Rog found this LA Times article today.
