Oops!
In today’s comic, I have the rain-stick thing as happening in Jaynestown, when it actually happens in Our Mrs. Reynolds. Once the comic’s in the archives I will probably change it, to save myself from getting email forever.
When writing the comic, I actually compiled a list of references to wood in Firefly by searching the scripts. They included Badger serving Jayne wood alcohol and Inara likening Mal’s sword technique to ‘chopping wood’ (both in Shindig). I should put it on Wikipedia so nobody has to duplicate my efforts.
