A fun fact about straw:
A "test conducted at the University of Nevada's large-scale structures laboratory showed that straw-bale constructions could withstand twice the amount of ground motion recorded in the Northridge earthquake that hit Los Angeles in 1994."
So if you happened to own a farm 11 miles from the San Andreas Fault, straw starts to look pretty attractive as a building material.
The state of California does not find this novel idea appealing:
The cards were stacked against Warren Brush, the director of a not-for-profit farm in Cuyama, California, when local officials learned in 2006 that he had several buildings made of straw bales on his land. They have tried to fine him. A lot. But the case is still unresolved. The problem is that California's building codes make no provision for the use of straw.
