I am a one-lady household and I very seldom have to give away what I can't eat to some very grateful friends and relatives. On that same note, it is a lot of produce. It does take time to clean and prep some weeks. Realistically, it doesn't take any more time than I would spend on a trip to the store and back. And again, it tastes infinitely better.
I could say tons more but really my best advice is to go down to the farm and check it out. Talk to our farmers Marta and Doug (and Alex!) and see what it's all about. Ask the members helping out any questions. Our CSA is a pretty awesome thing to be a part of!
