Well, what I would like to add here is something that I have heard from all of my north indian friends who have visited Kerala, ow they and that is, "hospitality" of keralites. I have heard them saying very good opinion about the auto rickshaw drivers and taxi drivers - how they took care of them, how reasonable the charges were, helped them in carrying their luggage and guiding them in their travel. Not even a single person, i know of, has complained about them when i have had very bad experiences with auto and taxi drivers from other states. I think hospitality of keralites is on thing that should be highlighted.
