I got to take a trip to NY City in May with kids from school. We visited the Jewish Heritage Museum and got a too-quick tour that concluded with a view of the Andy Goldsworthy exhibit on a terrace. In this project he drilled holes in rock and planted trees. He did test trials of this while affiliated with Cornell and those rocks/trees can be seen at the botanical gardens.
We also took a ferry to Ellis Island for an even briefer visit to the museum there. It was a great day to be on the water, the sky offered a dramatic view of the Statue of Liberty as we passed.
It cleared up and brightened up on the trip back towards Battery Park.
Ellis Island is definitely worth getting back to soon. 45 minutes was just enough time to get a taste of how interesting it is, particularly in my new position at work in the program for immigrants (see post below). They've done a fantastic job restoring the buildings and the displays are relevant and informative.
