The much-desired Glass House opening is the result of Johnson, who died in 2005 at age 98, bequeathed his entire property to the National Trust for Historic Preservation, while his longtime partner, art collector and curator David Whitney, who died in 2006, left a behest to support programming and ongoing preservation at the estate. I was lucky enough to order the ticket back in Feb 2007 for my May visit. Tours are available from May through October, the 2008 tickets were sold out few months ago.
