Last year I read an article about Community Supported Agriculture programs around the nation and became very excited about the prospect of joining here in SLC. I found one via this website and promptly joined. We enjoyed our experience immensely and signed up again for 2008. I am not sure how other CSA's are priced but ours, through East Farms, is very cost-effective. For about $10 per week you receive a box of freshly picked organic produce, straight from the farm. If you need to miss a week due to vacation plans, you can double up the following week. It's awesome.
