All interesting stuff being said here. I have not been there and have heard the horror stories but could someone furnish some photographs of the offending city. Maybe the airport, the airport terminal and downtown? I looked at the usual suspects like airliners.net but got little..webshots.com doesnt give too much either.
Slightly off topic, my dad has been to Lagos etc... and he tells me that NewYork and Lagos can be sister cities. Let me tell you guys, the majority of NYC is not nice! He tells me that East NewYork looks like Abidjan..
Living in NewYork most of my life I noticed we do many things here similar in Africa like.....not stopping at a red light. Dont make eye contact etc...
But dont worry, overnights in Manhattan are safe.
