Kollam is a beautiful old seaport and city in Kerala known for its breathtaking backwaters: it's so scenic that when you're floating down the calm rivers through the dense foliage you'd think you were on the set of a movie. David gets a chance to explore life in this verdant region: he goes digging for clams, he takes a tour aboard a floating restaurant down the river, and he cooks for guests at a local hotel.
