A sign that locally grown produce is becoming fashionable and mainstream is the phenomena of “cow pooling” or sharing a cow and made-to-order garden services that plant what the client wants and maintain the garden so their customers can have locally grown food without effort and time of growing a garden.
It is interesting that “locally grown produce to be the second-hottest American food trend, just behind bite-size desserts…”

It seems inevitable that services delivering fresh, local food to customers would spring up since many farm stands are in out of the way locations (although getting there is often much of the fun), farmer’s markets operate at inconvenient hours (often too early for city dwellers) and gardens require a plot and more effort than driving to the supermarket.
Deliveries could be more efficient in their use of energy, if a single truck made rounds to customers like the milk truck did in the mid-20th century, than the hordes of SUVs showing up every weekend on the farm to pick their own.
