So here's the deal. I got 6 hours of sleep last night, which is twice my average over the past week. I just got in to Denver tonight, and I'm exhausted. Tomorrow I have a series of press-the-flesh activities at the Denver Museum of Natural Science; a planetarium show about black holes is premiering, and my group helped fund and write it. So what I'm saying is I can't post anything tonight besides this note, and I may not be able to post until tomorrow night. This week has been incredible, but I may sleep for a week when I get home to make up for it.
