Look for the Tehama Gold olive oil if they have a booth there. It is a fabulous, organic Northern California oil produced by a family operation. If they aren't selling at the market, the Natural Store across the street sells it.
I can't wait for my annual jaunt to the market and my teenagers feel the same way ~ we plan our vacation around it and look forward to Thursday afternoons and the delicious after experience of savoring the food. The only problem? The produce is so good, we eat it too fast!!
