While visiting Greg and Jenny's new digs we took a 10 minute walk to Greensgrow Market. I had seen a story about this on CBS Sunday Morning sometime last year. In summary, Greensgrow is an urban agriculture farm and market on a once vacant one acre lot in an inner city neighborhood near the Fishtown area of Philadelphia. You can learn more about it here Link
On our last day in the Philadelphia area we visited the Peter Wentz Farmstead with Aunt Josie and Uncle Willy. In 1777 the Wentz farm served as headquarters for George Washington when he planned his strategy to keep the British forces from occupying Philadelphia.
