You cannot be a lazy or dull man and survive anywere in Nigeria but some places are known to be very rugged, sharpness n toughness is required, there are:-

5.)Onitsha
Anambra's commercial capital, is the biggest market in africa(even bigger than Lagos if u remove corporate firms). there r hungry boys who can steal from you smoothly, cheat u in market, and angry pepo ready to beat you for a little mistake of just blocking their way. if u want to stay here, b agile n don't b dumb

4.)Lagos
Lagos is not an easy place to stay, its overcrowded, busy, rough, u ve to jump into a moving bus, wake up before 4am n still spend 3 hrs in traffic, beware of 419 traders n criminals, thugs n armed robbers are anoda problem, pepo ve smart ways of cheating others, to even live here u
must b a smart hustler. I no many thought Lagos will b no 1, but bliv me, there r places worse than Lagos, apart from few cult groups, der really no big security challenge in Lagos.

3.)Port Harcourt
Not as crowded as Lagos, no much traffic and u don't ve 2 wake up by 4am, but ph pepo can b more aggressive than lagos pepo, u f**k up they f**k u up, Ph is not a place where mouth can help u without being ready to fight. u ve 2 b smart 2 avoid being cheated or unknowingly robbed, there r experts. as if dat wasn't enough armed robbers, kidnappers n cultists are all over, they've killed ph nite life n even commit day time offenses killing pepo n policemen daily. now mobile police hiluxs, SARS, SACS, roam every major street 24/7, with the military at various points, even the coast n rivers r full of navy men to keep dem safe, cuz militants n pirates nw eye des places.

2.)Benin-city
My own b-syd is d reason I can go anywhere else without fear, there's nothing our see there dat ve nt seen worse in Benin. In benin everybody must ve an inner agbero to survive. if u quarrel wit anyone u ve set u head 4 breaking, u c small children fighting n ready 2 break bottles on their heads, I was in a bus once, our driver was quarrelling wit anoda driver n d man spread wat was lyk tear gas in our bus n our driver almost lost control, in benin sharp boyz wil steal clothes from ur back n u won't know, der r professors of criminology n duping, cars r stolen evriday, houses sold, armed robbers n cultists are now outnumbering churches, yahoo boys(n girls)n kidnappers present, n security agents r almost powerless, SARS, Mopo r nw at evri 5 minute walk 2 search u n maybe clean(extort) u, the local vigilante is still der ready to catch n immediately der burn any kidnapper or cultist dey catch. knife n cutlass nor dey fear benin pepo, if u show dem gun dem go show u double barrel

1.)Warri
I thought benin was the worst, warri is the hideout of the smoothest criminals ever, u c pepo switching keys n locks to access neighbours rooms, small boys in crowded place foloing u wit razor blade 2 cut ur bag n take ur goods, soft n quick hands in n out of pocket, slap n collect, n oda genius criminal ways of cheating okada was stopped in warri because der were known for cutting chains on pepos neck n zigzagging away in the streets, in warri u suspect evribodi evrityme. if u r going 2 quarrel, ready to folo up wit fight, wafi don't lyk 2 tuk 2 much, children pick up iron rods 2 beat themselves, some throw demselves from storey buildings. armed robbers, yahoo boyz ,kidnappers n cultists nw make up almost half d population, secondary schools always fight holding guns, cutlass, daggers, axes, barb wires, acid, shooting, beheading n burning demselves n soldiers ve 2 stop d fight as spreads 2 town(police, SACS no dey near der), yahoo boys can b found in JS 3, n cultists in primary skuls(boys n girls). militancy ve nw added 2 d group n even d military can't handly dem. in warri nw, soldiers, SARS, SACS nw roam 24/7 in groups even entering residential streets, n nimasa n d navy roam the rivers n d coast, as kidnappers nw use d rivers as der nw rout. if ur wan rob real warri persin, e go still beat u wer hold dagger or gun, n na u e go rob.
