Another busy Universe day while Mark played poker in Vegas (with quite a bit of success). I went to all three lectures, and the morning one, by George Levine, was quite good, although none of the three lectures today were spectacular. We sold t-shirts again, so that kept us pretty busy before the lecture. And I helped tear down and tidy up the stage from the night before as well–but I did get a nap in in the early afternoon, so that was very helpful.
