Two things, quickly:
1) If you're in the NYC area, the American Museum of Natural History is hosting a Cassini exhibit, showing many of the beautiful images from the Saturn probe. You have plenty of time to see it; it runs through March 2009. Carolyn Porco will be giving a talk there in September, too.
3) OK, a third thing: my friend Karen Stollznow is hosting the Skeptics' Circle. I really need to start submitting to that. One more thing to do on a very long list of things to do.
