Have you noticed how gas prices keep going through a yo-yo effect, but the trend just keeps getting more expensive. If you remember 2008, gas prices were on average at $3 a gallon at the beginning of the year and jumped to over $4.5 a gallon through the summer. The increases in gas prices was taking a big toll on many of my friends and families wallets. But not mine, I purchased a CNG Car (compressed natural gas) that not only saves a load of money (only an average of $0.75 a gallon equivalent through 2008) but is far and beyond a cleaner solution for the environment.
