Saw the Dale Chihuly exhibit at the De Young this morning. Member check-in right at opening time--the only way to do it. This was the coolest piece--a room where the ceiling held hundreds of blown glass objéts, through which the light filtered. Otherwise, I liked the show okay but didn't love it; it was kind of decorative for my taste.
And by the way, there appears to be a new rule at the De Young prohibiting tripods. No flash and no tripod--the rule appears to be that you can take pictures as long as they're really crappy.
