There are some 1000 or so houseboats on Dal Lake in Srinigar, Kashmir, India. The vendors show up at dawn and the buyers show up a little bit later. All transactions take place on the water in the small wooden boats; there is no way to sell to people on land. This is definitely not a tourist market.
Being winter, the items for sale were generally root vegetables and other winter vegetables.
We were shooting for about an hour, when the weather turned and it started to snow, and the buyers and sellers all disappeared.
