From The Boston Globe:

This weekend, though, fans of the public Newport can get glimpses of the private Newport, in its gardens if not in its homes. A tour organized by the group Benefactors of the Arts has gained access to the grounds of the New York Yacht Club and six private gardens, including one owned by retired US senator Claiborne Pell and his wife, Nuala, and another across the street that was once owned by author Edith Wharton.
