What Took 6 Yrs. in 1980s Took Only 6 Mos. in '08

To put the recent fall in gas prices in perspective: It took more than six years for real gas prices to fall from about $3.50 per gallon in the early 1980s to $1.72 in early 1986, and it took only about six months for real gas prices to fall from about $4 in June 2008 to $1.72 in December 2008.
