Spent much of the day on a ferry from Alleppey to Kollam, another town down the coast. The ferry uses only inland canals and lakes.
On arrival, we got into a procession with brightly lit animatronic Gods on floats, drummers, dressed-up people with oil lamps, torches, and several elephants. All with incredibly loud Indian music from tortured loudspeakers. It's called the Devi festival.
