So after some serious time spent staring at the internet until I realized the reason I was feeling dull might have something to do with the fact that I'd only eaten (very) crispy bacon and cookies, and then I went to buy some coffee and a bagel. And at that point I was halfway there, so I kept walking! ^_^
BTW, you can click on any picture to see it BIG. If that floats your boat.
I walked past this, which is the outside of the High Court. They have what looks like a moat, three stories deep, with barred windows opening into it and a rusted cage at the top. Very cheering, I'm sure.
