The price of gasoline has dropped 11.7 cents in the past two weeks, placing the national average at around $3.98 per gallon according to GasPriceWatch.com. The drop mirrors a decline of an estimated $20 per barrel in oil prices over the last two weeks. This is the first time gasoline has been under $4.00 since June 5, 2008. Some believe a continuous decline in gasoline prices may inject a much needed boost into the stock market. The market has been under tremendous pressure in recent months as investors are concerned about the impact high energy prices currently have on the economy. Its been speculated that the decline may also aid Detroit, a city that has a huge stockpile of SUVs and a number of automobile factories in jeopardy.
