Signs of New York's long timeline can be found most anywhere. We pass them by everyday, and mostly we don't notice. I was recently struck by this loading dock in Tribeca. Not the bricks or the roller-shutters, but the lip of the dock, which is composed of long, bare, gnarled logs of untold age. They look prehistoric to me, and we set in place decades ago by some huge piece of metal (large nails, hooks, spikes, I'm not sure). Come hell or high water, I'm betting they'll still be here.
