I just finished Animal, Vegetable, Miracle by Barbara Kingsolver and was impressed by her tenacity and resourcefulness in eating local for an entire year. Not to mention that it made my garden seem incredibly small and unproductive compared to hers, but I am proud to say that I can see ripening tomatoes from my kitchen window. We live in a farming mecca here in California and it is becoming easier to find locally grown food through sites such as Local Harvest, Slow Food USA, and CA Farmers Markets.
Lately I've been going to the Marin Farmers Market on Thursday mornings, which is one of the biggest markets in the Bay area., to purchase as much fruit as my basket and fridge can handle. It's nice to be able to see a wide variety of vendors selling amazingly ripse vegetables, fruit, flowers, condiments, breads and cheese. It puts grocery store tomatoes to shame. Last week's purchase included Purple Peruvian potatoes from The Little Organic Farm in Petaluma and Nicasio Reserve, cheese from Nicasio Valley Cheese Company. The market is certified and maintains a strong goal of promoting local agriculture through events like Eat Local 101 which inspires you to enjoy food from local farmers, to gain a deeper appreciation of where your food comes from, and the economical impacts when you buy from local farmers.
If you're really serious about eating local then join the Locavore movement which challenges you to buy food that is grown within a 100 mile radius of where you live! I've also found a few Iphone apps to locate markets like the Farmer's Market Finder, Farmer's Market Companion, and the HarvestMark Food Traceability that helps you find where your produce came from.
