Well, it aint worth a hill of beans, but the trend for gas for the last 5 years has been upwards. Like 2.33 times more expensive now @ 4.09/Gallon. Projecting the same rate of increase would put it at $9.56/Gallon in another 5 years so maybe the 5 year figure should be more like $7.00 a gallon? But for a lot of folks it is more than just about money, believe it or not.
