DISCOVERING DISCOVERY BAY: Disney buffs -- many of whom are members of D23, the for-serious-fans club that began in a big way last year -- like to know everything. We mean everything, and that includes being privy to park plans that were never fully realized. Architectural specs, drawings, paintings. There's a new calendar revealing proposals and art for a number of never-realized projects, including Discovery Bay at Disneyland and the Switzerland Pavilion at Epcot. In a word: cool. GET IT: It's available to D23 members. Find more info on membership here.
