I took a class on optically stimulated luminescence dating, where we worked with the University of Nebraska professor who does a lot of work on the Nebraska sandhills with Joe Mason, a prof here in geography. It's really cool work- they can tell when the dunes moved, and where they came from, and how fast they formed and moved. We drove around Illinois looking at dunes- it's funny, because many of the houses are built on them because it's a nice high place, and I'm pretty sure there's no such thing as dune insurance.

That story about Garfield is mindboggling. I always wondered how he managed to survive for 80 days. How sad.
