Farm to School

I was thinking about a friend of ours who used to work for Portland Public Schools setting up school gardens.  She was doing Ameri Corps and I noticed, when serving myself, that there was a push for host sites that fostered farm to school programs.  I found this site, which showcases some current programs nationwide (no surprise here, Oregon is really into farm to school).  It sounds eerily familiar though, connecting farmers to school children, ensuring farm viabilityandnutrition, while respecting each community’s specific needs (no regulations here folks).  Of course implementing a farm to school program depends on state laws and regulations, but is this just another lunch program that provides for middle class students (and farm subsidies)?  Could something like this work in Philadelphia?
