I recently went to Portland, OR on vacation and stopped by the Ecotrust building. Not only did I enjoy some damn good Hot Lips Pizza, but I got to pick up some useful resources and to check out the beautiful building.
One of the Ecotrust resources is the Eat Local Scorecard:
I thought this was helpful for actually tracking the incorporation of locally harvested and produced foods into your life. Even if you don't use this scorecard, it helps conceptualize how you can start introducing these foods into your diet.
