I just read that Clarion River Organics is offering a 6-week, Peak of the Season CSA featuring the best of the summer's bounty. This is a great way to try out a CSA to see what you are interested in and whether or not the model works for you. There are two size/price options as well - both incredibly reasonable for what you'd pay for produce at the store - and this is the best our area has to offer! Check it out here.
Starts the first week in August, so hop on it!
