Common Ground is published in LA, Seattle, San Fancisco, and Chicago.
This is a great overview article and mentions numerous communities throughout the country.
I love this quote:
Dave Henson has a garden he can’t afford, a restaurant-grade kitchen he can’t afford and a hot tub he can’t afford. He’s also managed to find a way to reduce the number of hours he has to be an on-duty parent — without having to pay babysitters.
That’s because Henson lives at the Sowing Circle in Occidental, CA, one of hundreds of intentional communities in the United States where singles and families are surrendering part of their much-vaunted freedom in order to live with others.
