Nostradamus they're not

About five years ago, USGS published a very fine brochure entitled, " Natural Aggregates–Foundation of America's Future." In that brochure, it was predicted that aggregates production would reach 2.7 billion metric tons by 2020. Whoooops! About 16 years off there. Aggregates production crossed the 2.8 billion threshold last year. This just serves to underscore the expansive nature of the aggregates market, and the incredible run that producers have enjoyed over the past decade. Your comment?
