Once known as communes, until the word became overly associated with hippies and other cultural relics of the 1960s and ’70s, intentional communities have a long history in this country, going back to the Shakers and even, I suppose, the Pilgrims. I’d long wanted to visit one, to see how utopian ideals were surviving in the more cynical America of today, and so I logged on to www.ic.org and searched for intentional communities in Wisconsin and Iowa. At first, I found what I had expected: devout Christians, pagan farmers and a polyamorous “family” (my wife, Jean, vetoed that one). Almost all, however, wanted serious members, not casual visitors like me.
