Gas Prices

I believe that the gas prices are low now but will increase little by little. I really don't know why the gas prices are half the price now becasue I remember in September I paid $4.01 a gallon for gas and on Monday, I paid $2.05. This saves me alot of money and I like it but I won't keep my hopes up becasue anything can happen in this economy. I believe gas prices were $5 dollars a year ago because of President Bush and they way the economy was. If we have low gas prices, the economy is doing bad but if the gas prices goes up, our economy is doing better. It goes either way but hopefully it can stay in the $3 dollar range and not any higher. I don't think I can afford $4 dollars a gallon.
