What City is really "HELL ON EARTH"?
I am a strong believer in reincarnation. People that had it great in one life and blew it by being a terrible person- will be reborn in a terrible life in a city that is truly "HELL ON EARTH".
I read about how terrible many places are on this planet, but the true story about it is usually hidden behind political correctness.
I suspect that the travelers on Flyertalk have been to some terrible places and have some great stories to tell.
To start things off my vote goes to Lagos (in Africa).
