We had a similar experience with our local CSA doing a 1/2 share; there are only two locally btw and only in the summer season. We loved the quality of organic produce, but it just wasn't worth the money, as we still needed to purchase regular salad veggies weekly. I almost switched to the other one, but after reading the on-line blog from last year that mentioned what was in the box each week; that was pretty much the same as the other CSA...
Well, we would be pretty much in the same boat. My family is pretty adventuresome, but we are daily salad eaters.
