Exactly as kenratboy said it. I think right now, I'd just like to see more skyscrapers and taller, much taller.
Theres some of the Bay Area that I would think can never have tall skyscrapers because of the nearby airports and thier FAA height regulations.
Its hard to imagine SF like Hong Kong but I think a comparision between SF and Chicago are more realistic. Not that its a downturn because Chicago has some nice architecture too.
