The worst five of sixteen destinations by degree of danger: Bogota, Columbia, Mexico City, Mexico, Lima, Peru, New Delhi, India, Jakarta, Indonesia.
Bogota is about a days donkey ride from drug cartel country. The same applies to Mexico City where kidnapping foreigners for cash is a whole cottage industry.
Lima has so much danger it's astounding anyone, man or woman would go there even if it led to a lottery prize. New Delhi is diseased, depraved, debauched and gang rape central. And finally Jakarata. This is the place a woman can end up in prison for refusing a taxi cab ride.
Scared yet? Think you can do better in Paris, Beijing and London? Keep going, those places are on the list of sixteen too...
