Andy Berlin of Berlin Cameron/ Red Cell hosted friends and colleagues aboard his boat, The Traveler, over the Fourth of July.

Joy is the story of seven friends who discover their own unique love of life, each other and themselves in San Francisco. Its title has been shortened from The Joy of Gay Sex. ... Anna Kournikova has always been a better endorser than tennis player (and now that she's writing a column for Elle, she might prove to be a better writer as well).

"It still is a definite possibility, but I really don't know what's going to happen yet."
