I haven't filled my '97 Ford Explorer up in a while. I usually on fill it half full. I get 12 miles to the gallon and it is 12 miles one way from my home to work. Each day costs me 2 gallons of gas. The higher the gas prices go the more sense is makes for me to ride. In LA I have seen gas prices from $4.17 to $4.90. So Pay $8 to drive or save $8 and get healthier? I pick saving it.
