On a Sunday morning, whilst at church, I got a call about a black snake in a yard in Randberg ( a town just north of Johannesburg). Usually a black snake in Johannesburg in the day time is a Rinkhals (a common type of Spitting cobra).
As it was rather far from me and I was at church, I refereed it to a group of snake catchers.
It turned out being a Black Mamba. As they are not naturally found in Johannesburg, it must have been an escaped pet or trans-located by accident.
Either way I missed out on a great opportunity to catch Africa's most dangerous snake.
