I'd suggest giving them a call or perhaps emailing them; these maps questions are not generally sent to the business owner.
They seem to have a lot of product on hand so I have faith that the drive wont be in vein. I haven't found their feta in stores myself so not sure where you can get it.
Many people who answer these are from the public, perhaps folks such as myself who have visited often. So clearly we don't have power to hold a certain amount. However, I've traditionally see that they have plenty on hand. I cannot answer where else Harley's farm goat cheese is on sale.
How far is the farm off hwy 1–is it worth taking 6 friends to stop by the little shop and to see the goats on the way to half moon bay?
