One of the perks of being an old NM resident is that I can take University classes rather cheaply. I took Playwriting and Human Genomics this semester, and they were pretty fun.
Looking around for next semester. The math department has a graduate course in Measure theory, which I really should know more about, just for vanity purposes - Measure is my name after all. On the other hand, it does sound a bit boring, and I'm not sure if I really care that much about Lebesgue Integration. Astronomy offers a graduate course in Galaxies, which might be fun, but the problems might be hard.
