I found this linked from the OpenMap project (that rumbling sound you're hearing is the FOAF weenies getting excited) which is also pretty cool.Local Harvest maintains a definitive and reliable "living" public nationwide directory of small farms, farmers markets, and other local food sources. Our search engine ... helps people find local sources of sustainably grown food, and encourages them to establish direct contact with family farms in their local area.
