Well I never watch TV, but this might be a reason to turn it on for a couple nights. PBS is going to start playing a 3-part series based on Jared Diamond's Guns, Germs, and Steel, in which he argues that geography is a primary cause for the rise and decline of nations and cultures. A good read, and should make for a decent documentary. KETC will show the 2nd part first at 9PM on Monday, and then follow up with the 1st part at 10. If you want to watch it in series order (as I think I would prefer), check out their schedule to find a time that will work.
