Depressed about diesel?

Diesel fuel prices are killing aggregates operations. I found an amusing article in an issue of Pit & Quarry from 1981. There was much consternation because diesel had risen from 15-cents-per-gallon in 1971 to 85-cents-per-gallon in 1979. The article predicted, with much forboding, that in the future the price would hit $1.45 per gallon. Damn, that sounds like a gift heaven right now, doesn't it? Your comment?
