John Chang is the founder and director of Peaceful Morning Farm.  He studied small-scale sustainable agriculture at the University of California, Santa Cruz Agroecology Program and has grown for farmer's markets and CSAs in California and Washington state.  It's not just the harvest that motivates him to farm, but also the community that is formed around local, volunteer agriculture.  His favorite way of telling people he cares about them is to hand some food he's grown.
