Anyone else like me and just can't get enough of this place? I've been there 4 times and counting this past week and have not seen it all, but I love the atmosphere of the place. I think I'll make this a weekly outing if I have the time.
JFSebastian -- yes the pass is definitely worth it; also discounts on the special events.
The folks I've gotten to know who work there say there's lots of awesome exhibits to open soon, perhaps January 2010, though they may be temporary ones. The second building, I believe, is scheduled for 2012.
