There must be more economical ways to spend money for San Francisco public space:
Here's a plan for "a cable-car-like people mover between a half-acre plaza and the rooftop park planned for the city's new transit terminal." SF Chron columnist John King, who does care about these kinds of public spaces, quotes Paul Paradis, a senior VP with developer Hines, as saying, "We think
it's a great way to show people there's something to go up to, and a
terrific attraction in and of itself."
Redwood trees on the roof, too.
Sitting here boggling at the money this idea would cost, how popular the result would be, and what else the money could be spent on.
