If the Montreal Forum, the most historic sports arena in the history of sports this side of Yankee Stadium, could be torn down, and seats with Stanley Cup Banners auctioned off, Candlestick Park can be made landfill no problem.
(And yes, they did auction off the original Stanley Cup banners that hung from the rafters. The Bell Centre was too big for the old banners, so they made new, bigger banners when the Canadians moved.)
