I just read the Riv Reader (thanks!) and answered my own question. Queue epic tension building music. "In a world ruled by engineers, who decides if the size of the tire is based on the rim or the outer diameter of the tire? No one. Such things do not matter to engineers and they rule the world. So they shift whilly-nilly and 603 suddenly stands between 650 and 700. Is all hope lost for the commoners? No. In a quiet hamlet near San Francisco (where the Golden Gate Bridge amazingly measures a span less than the body of water it crosses*) a steel clad retro-grouch rises from the measuring stick ashes. GP (whose brain measures a greater volume than his skull**) gathers a small band the confused but willing (whose numbers greatly exceed the hoards they oppose***). Will it be enough ... to save the world?"
*(Golden Gate bridge measured in millimeters, body of water measured in inches) **(brain volume measured in drops of water, skull volume measured in balloons) ***(Small band measured in number of cells, general population measured in bundles of 10,000) There. That's my cognitive therapy for the month. Possibly year. Whichever is bigger.
