Both existing and future. Gonna have to start growing yer own food. From NYT which lists it currently as amenity. But, someday it will ratchet up one notch to necessity:
At the 220-home Serenbe project near Atlanta’s airport, the cachet of local produce has been added to retiree-friendly businesses, including galleries, a bed-and-breakfast and three restaurants. Steve Nygren, an Atlanta restaurant impresario, started the project on his 900-acre farm.
The problem is that this is still in “niche market” phase serving a solitary demographic.
