Christo speaks, answers Goldsworthy

Christo, international art star, gave our correspondant a sneak peak at his latest installation deep inside The Presidio, San Francisco.

Rumors of a rift with Andy Goldsworthy, whose "Treeline" project is embedded in a stretch of Presidio forest, were squelched by the amiable Christo. "Who is this Andy Goldsworthy", the artist is reported to have said.

Privately funded, seven years in the making, the wraps come off Christo's latest, summer 2011.
