Back to the Garden, Flower Power Comes Full Circle :

In 1988, director Kevin Tomlinson interviewed a group of back-to-the-land hippies at a “healing gathering” in rural Washington state, practicing peace and love. Now, in this poignant examination of this community over time, he tracks down those original interviewees and their children twenty years later to find out what the glories and sufferings of living out of the mainstream and off the grid might really look like.
