Take advice from your people on the scene and follow it and you should do fine.
Any outing in Nigeria has a certain level of risk to it, but are you going to just sit in your room because of that?
I was in a Lagos crew bus that got shot up, yes. But that was on 10 September 2001. Would I have been safer in downtown New York?
Just remember; it isn't the bullet with your name on it that you must worry about. It is the one addressed, 'To Whom It May Concern.'
On the other hand, play the fool in Nigeria and it may end up costing you big bucks. There are sharpers and cutpurses aplenty there who can see you coming from a long way off. Just like New York, in fact!
