On the airplane I got ministry-related reading done, and enjoyed looking out the window at the snow and clouds covering the landscape below. I also had time to read some Terry Pratchett. I like the "Watch" subset of Discworld novels best.
Here's some interesting commentary. I had never realized Vetinari's name was half a pun.
Vetinari is such a great character. There is a man whose life expectancy was linked to education.
UPDATE: Why are the Discworld novels so neat? One reason is that none of their plots are nearly identical remakes of old ones (warning: link has profanity).
