From another tipster chum, we learn that Nairobi's increasingly famous banana yellow Humvee is owned and operated by someone named Charles, said to be "one of the main IT people at the UN." Here's hoping that Charles will submit to an interview (all in the spirit of good fun, of course -- this isn't Darfur or anything).
PS: I was driving on James Gichuru Road the other day, climbing the hill as it approaches Wayaki Way, and what should I see hurtling in the opposite direction? You guessed it, the B.Y.H! I caught only the briefest of glimpses of the driver (was that you, Charles?), and considered turning around and following him. But there were two other passengers in our car, one of whom happened to be an eight-month-old baby who was angry about being 45 minutes late for a one-year birthday party. Next time, Charles! Next time!
