Buffalo Park is a cricket ground in East London, Eastern Cape Province, South Africa. It is one of the home grounds for the Warriors cricket team. It can hold up to 20,000.
It has hosted one Test match, in 2002 and hosted a number of One Day Internationals.
It was once also known as Mercedes-Benz Park, thanks to sponsorship from the German motor manufacturer.
Here's a tip for newer players. Read all of the information given by the poster. In order to solve Admiral's challenge about Nauru, I homed in on the population, which he gave exactly. I figured that there would probably be no other places in the world with that exact number of citizens at that time.
My Google search was simply "population 9322 in 1968". The rest was a simple copy and paste from Wikipedia.
