For those who have not visited or lived in Kashi. You can visit a city as a tourist or traveller, but you will never experience it as a resident does.
However, as far as reasons to travel are considered, visiting for religious reasons is as good as any.It should be treated as the 8th wonder how a such a holy city can have such a crook civilisation. Then I remembered that Shiv ji is surrounded by a bunch of ghouls and ghosts only. Quite apt for its citizemry.
