Cheesecake, an experiment in communal living, ongoing after 20 years.

"Of the original 11 members, seven are still here... The community has taken on new members, so there are now 13 altogether. No one seems lonely..."

In matters involving the environment, Ms. Otis said, the community is divided into two camps: “Some are Druids, those who don’t want to change anything, and some are foresters, who can cut the brush back. Jill and Gaile are the Druids.”

Gaile Wakeman, a retired pediatric physical therapist who is 76, concurred. “I don’t want a single tree to be cut.... I don’t give on this. You cannot replace a tree that’s been here 300 years.”...

The other thing residents tend to disagree about is money. And as is true elsewhere in the country, Ms. Otis said, “conservatives are those who do not want to spend money, and liberals do.”

But while these distinctions may resemble those between Republicans and Democrats, Ms. Wakeman noted, Cheesecake members lean to the left politically. “We’re all pretty liberal,” she said. “A Tea Party person would never live here.”
