We've gotten a weekly box from Two Small Farms for a few years now and will keep getting it as long as we live near a delivery site. They have excellent quality, reasonable price, a constantly-changing variety of fruits and vegetables, and a weekly newsletter with recipe suggestions.
I love our CSA. I have learned about produce that I had scarcely heard of before. Keeps our diets on track and we love supporting our community farmers! Not to mention new things to try in my garden :-)
I love my weekly vegetable box from Mariquita (aka Two Small Farms). The veggies are fresher and crisper than most stuff at the farmers' market, the newsletter offers a variety of ideas for how to cook things (along with fun stories!) and there's often some new vegetable that I've never heard of before, let alone tasted (orach? agretti? lovage?). It has really changed the way my family eats.
