Kevin, you recommended the logistics chapter in `Swords` to my attention. I am now reading some fascinating comparisons between the logistical systems of N and W (mainly in Spaln) in Arnold D Harvery`s `Collision of Empires` on google. Pages 143 onwards are MOST interesting; they may sound a little familiar to you, but they don`t sound much like `Swords`was meant to, heh, heh, heh.
