All I reall saw of Lagos was the 20min bus ride to and from the airport.
We got escorted by Police & had security guard and his trusty rifle on the bus with us, briefed us about keeping windows/blinds closed, if rebels take over then we can escape out the back but dont negotiate with anyone.
It is such a poor city and everything was run down, slums everywhere. People were so poor they were selling chewing gum on a board for cash.
