Chicago - Let's eat local!

Chicago is setting goals for local food purchasing to reach 10%-20% by 2020. A local stimulus bill is being set into motion to help train locals to go into agriculture and hopefully this means diversity in its crops. Currently, the main products of Illinois' are...you guessed it - corn, soy, and hogs. Wouldn't it be great to have a state produce mostly heirlooms? Is that possible? Yum.
