The inspector at the plant is the same for all batches generally. and thus subject to bribe. a "Surprise" inspection (unannounced) has caught a few of 'em with their quality down.

Michigan did a few miles of road WITHOUT federal assistance.. Lasted longer than the Federal funded.. Wonder why? (I used to work in a shared office. one of the occupants. actually the owners. Michigan State Departent of Transportation Project office where new and exciting innocations in freeway construction are born.. This office was straight out of a Science Fiction Movie. only it was not fiction. it WAS however SCIENCE (Yes I saw the movie)
