I'd be dangerous.
Yesterday, I realized that I could get some world design done ay work. After each round, I take a few minutes to rest, maybe have a Coke, or read. It would take me about ten minutes to chug out a basic planet design.
So I load the book bag with GT: First In, The Regency Sourcebook, Adventure 4: Leviathan, paper, pencils, a map of the sector, and even three dice.
I remembered everything.
Except my calculator.
Since I can't do fourth roots in my head (or even on paper) I ended up hauling a whole lot of weight for nothing.
Well, at least I got to have a BMW towed...
