The farm that we joined is North Star Orchard, based out of Cochranville. Their primary focus until about 3 years ago was fruits, but they have a huge variety of vegetables as well. You sign-up now (February - April, depending on your specific farm), pay for the produce, and wait. But, you get to lock in the produce at a set rate, and regardless of how high the prices may rise at the grocery store, your price can't change because you've already paid for it! North Star does vegetable and fruit CSA shares, although I only signed up for the vegetable, because I don't think we would eat that quantity of fruit, but am more comfortable with the veggies.
We chose to pick-up our vegetables on Thursdays, and the pick-up location is about 10 minutes from home and is open from 4pm - 6:30. Something really exciting is that North Star is also partnering with a local bakery and a gardener, so we will have the opportunity to pre-order baked goods (muffins, pastry, bread, doughs) and flowers (cut or to plant) throughout the summer. Our season will run 22 weeks, and will start the last Thursday in May.
So... here is the list of types of vegetables we may see throughout the summer. I'm going through cookbooks now to get some ideas, and am excited already!
