I like the painterly juxtaposition of the splash of red, from the (ubiquitous) Olympic poster at lower right, with the chemical gray-brown-ochre of what lies above. It's not fog.
I'll keep taking such pictures but will stop posting them. The point is made. But while I'm at it, a couple more after the jump.
These are both the same general area shown in this shot three days ago.
That is enough from me on this topic, at least for a while. But, seriously: how is this not an all-out emergency from the Olympic committee's point of view?
