While the chips of stone sitting in your roads and driveways may be small, the industry which makes them sure isn't. Last year, in the United

States alone, construction sand and gravel valued at $5.8 billion was produced by around 4000 companies running 6300 operations in 50 states. Of course, the nasty rash that results when you fall on the stuff is no laughing matter ... just ask any kid with a BMX.
