Sierra Magazine featured four urban farmers from my book Backyard Roots for their annual Food issue! Above, Jonathan Chen, became the director of the Danny Woo Community Garden in Seattle after surviving cancer as a college student. He worked with immigrants in the terraced downtown garden and introduced a kids program and chickens. Other urban farmers included Alex Winstead, an organic mushroom farmer who began his career as a hobby growing mushrooms in his basement, Rachel Hoff and Tom Ferguson who lived for a year without setting foot in a grocery store and Lee Kindell who introduced kids to aquaponics at his downtown hostel.
