It took me a few years to get there, but here's the interior of the World Trade Center transportation center, also known as the Oculus, designed by Santiago Calatrava.
Monday I was looking through architecture photos online and saw an interesting photo of the exterior. It reminded me that I'd always wanted to go back there after it opened, but the few times I've been in Lower Manhattan in the past few years -- for classes or jury duty -- I never had time.
Now I've got nothing but time, so I hopped on a bus and went downtown on a whim. It was a clear sunny day, cold (because January) but not unpleasant with a cup of hot tea in hand, even by the river. I walked around, drank my tea, took some pictures, then got on another bus and came home.
I loved being able to do that.
