In the winter of 2009-2010 I was  working on how to collect Sycamore (London Plane) sap from all the street and park trees in New York, and boil it down for Sycamore syrup, which reportedly is like maple syrup, but a little more “mediocre.” I documented that project along with some other related thoughts and experiences in a work called  We Common, published by ISCP in an exhibition catalog Out of the Blue, and online at the Center for Collective Wealth.
