City of Sound posts a very interesting take on the effects of the APEC security zone on the urban and informational fabric of Sydney.

"Actually, it is of course fascinating: I overhear people talking of going to actually see The Fence, as if it were a new temporary attraction, and when I visited on Wednesday, many Sydneysiders were just hanging out in the "sniper-ridden ring of steel", watching the whole circus. News sites are full of it, and Sydney has been radically altered for a few days. There is plenty to see."
