The Donkin Reserve flag in perspective

I have posted a couple of pictures in the past that included the enormous flag pole and South African flag standing on the Donkin Reserve and whenever I tell people that the flag is about as big as a tennis court they tend to look at me in disbelief.  Well, viewing the Donkin Reserve from on top of one of the buildings in the city centre the other day I could actually photograph the flag and put it into a better perspective
