"The [Rainbow] gathering is organized around large camps and communal kitchens that serve coffee, tea and food. No money is exchanged."

"At a trading post, kids and adults bartered for jewelry, stones, glass pipes and Snickers. A painted rainbow was being erected over the 'Granola Funk' stage in the meadow, where a musical, a gong show and other performances would take place. At the Christian-themed Jesus Kitchen, one attendee said the nondenominational gatherings had made him a believer. 'I’d never seen Christians do it the way these guys do it,' said Gavin Boyd, 25, a carpenter from Fort Collins, Colo. It was, he said, less orthodoxy and more spirituality."

This weekend is the 50th Anniversary of the first Rainbow Gathering.

Most of the WaPo article is about the locals worrying about the environmental impact of the gathering and the group's basically good reputation for sanitation and cleanup. There was a little something about politics:

[I]n a nation that often seems to be divided in two, the Rainbow Gathering’s half-century assembly told a story of many Americas.... Attendees skew left but probably also include a few “Trumpsters” and QAnon devotees, said one longtime camper. The era’s political divisions, in any case, did not dominate conversations. 

“You have the whole continuum of people,” said Ray, 70, who on Friday was pulling a 100-pound cart of supplies up the 1.5-mile trail from a parking area to what is known as the Main Meadow, site of communal dinners and the event’s pinnacle, a July Fourth silent peace prayer and meditation....

“There’s also politics here. The right of the people of America, United States, to gather peacefully — that’s supposed to be a right — on the people’s land… To practice spiritual belief, freedom of religion,” said Ray, a retired health-care worker from southern Oregon. “To assert those rights at a time when, in my view, fascism’s grip is getting tighter and tighter and tighter.”

Here's the group's webpage. And here's their video:

 

Meade overheard that and said "Sounds like something from 'South Park'... Tegridy Farms."

Here's the Wikipedia page, "Rainbow Family":

Rainbow Gatherings emphasize a spiritual focus towards peace, love, and unity. Those who attend Rainbow Gatherings usually share an interest in intentional communities, ecology, New Age spirituality, and entheogens. Attendees refer to one another as "brother", "sister", or the gender neutral term, "sibling". Attendance is open to all interested parties, and decisions are reached through group meetings leading to some form of group consensus. Adherents call the camp "Rainbowland" and refer to the world outside of gatherings as "Babylon". The exchange of money is frowned upon, and barter is stressed as an alternative.... 

Participants make the claim that they are the "largest non-organization of non-members in the world." In addition to referring to itself as a non-organization, the group's "non-members" also even playfully call the group a "disorganization."

Hippie humor. It never changes. 

This use of the rainbow predates the LBGTQ use of the rainbow, which began in 1978. But it doesn't predate the Rainbow People's Party, AKA the White Panther Party, which began in 1968 in Ann Arbor. And it doesn't predate the Rainbow Coalition, which began in 1969 in Chicago. And it doesn't predate Rainbow/PUSH, the Jesse Jackson group, which began in 1971.
