Tanaka is a working organic farm in the middle of Irvine (right by UCI, who would've guessed?). Not only do they sell wonderful organic produce at their farm stand, but they have excellent programs for kids (or anyone interested in how farms work). They have strawberry picking in the Spring and a huge pumpkin patch (really a pumpkin field) around Halloween. They do a whole tour with these events, and kids get to pick their won produce. There may even be other events during the year, too. This is so much better than taking your child to a parking lot to pick up a pumpkin. This way they really get to see how the vegetables and fruit they eat are grown. It's a very special place.
