There was an IZ marathon one morning, (rare morning that I was driving to work). This is the same route I take walking. The runner's are tiny blips and the photo quality not so hot - I include these mostly to show you what the IZ looks like. Before coming, I'd assumed it was a bustling city-center.
Hardly. This was mostly Saddam's private retreat and its environs, GOVT Buildings, Palaces, etc - off-limits to 99.7% of Iraqis.
And you don't want "bustling" in the Mid-East. Trust me. The city outside our T-walls teems with gnarled traffic, street commerce and sewage and trash. As you can see, the IZ itself is criss-crossed with T-walls. Not so much suburban as much as a labyrinthine white-collar prison. You have environs - you just can't see them - until you pass through the particular security gate.
