Again: Does Oprah Winfrey still believe in the global warming hoax?

Oprah Winfrey goes house-hunting along the Hudson, including at the $68 million mansion on the grounds of the former Frick estate - NYPOST.com

Among the homes on her must-see list: a $68 million manse on the sprawling grounds of the old Frick estate in Alpine, NJ, the sources said.

Oprah's three-car caravan, including two black SUVs and a van, pulled into the ritzy enclave before noon yesterday, a source said.

The billionaire then toured the 30,300-square-foot, English-manor-style mansion, which is part of the lavish "Estates at Alpine."

Workers and others on the grounds were asked to make themselves scarce while Oprah checked out the five-story, 19-bedroom and 12-bathroom spread, according to one source.
