People Power Granny: Can Intentional Communities be the Answer to this Messed-Up World?:
One good example of an intentional community that left the rat race but not the world is the Farm in Summertown, TN. Started in the early 70's by a 'family' of hippies, this community today still is alive and well. But in its 30-plus years of operation, members have gone out into the world to help the suffering, have provided training for the re-birth of midwifery, have created a watershed protector of their local river and have introduced kids in the cities to life on the farm. This community speaks out against illegal wars and other injustices. They have incorporated the internet and other new forms of communication to get their messages out to the world. As a matter of fact, residents of the Farm are often leaders in the world fighting the Powerful.
