I have no idea what this is...

But it was more interesting than South Street Station.Which was as far as I walked after getting out of the conference before the drop in temperature since lunchtime and really amazing wind gusts sent me back to the hotel ! The financial district is hard to navigate as the streets are the least orthogonal I have seen in Boston and that is saying a lot!I wound up at the Commons briefly at lunch but haven't been able to figure out how I did it. I am directionally challenged.
