There are only a dozen or so Certified Organic vegetable farms in Missouri which is another reason why Happy Hollow Farm is so special. Liz and Katie raise their two kids there and the place has evolved every year in infrastructure and offerings. CSAs work by memberships and as you can see at the website, there are several options for membership. High tunnels make some veggies available year round. Partnering with other organic providers gives variety to what can be offered to members and sold at the Farmer's Market in Columbia.
