Not only do they own some of the hippest hotels in Miami Beach (the Albion, the Greenview, and the soon-to-open Beach House in Bal Harbour), but the Rubells -- Mera, Don, and offspring Jennifer and Jason -- together possess the finest private collection of contemporary art in Florida. "There are few collections of its equal anywhere in the world," insists David A. Ross, director of the San Francisco Museum of Modern Art. "I'm jealous." Many of the works, too big or too daring for the average museum, reveal this family's taste for the strange, humorous, and irreverent. The paintings, installations, photos, sculptures, and videos by artists such as Paul McCarthy, Keith Haring, Francesco Clemente, Sherry Levine, Jean-Michel Basquiat, Charles Ray, and Cindy Sherman are exhibited in a former warehouse once used by the Drug Enforcement Administration. There is no fee for admission, but be forewarned: This stuff hasn't passed the censors. One depicts dozens of naked mannequins sprawling on the floor engaged in oral sex. In another a young boy is encouraged to get it on with a goat. Bring the kids at your own discretion. And risk. The collection is open Friday through Sunday from 11:00 a.m. to 4:00 p.m.
