4 vehicles is a start and some are better than none. Hard to understand why
natural gas is not used more. A semi using 20,000 gallons a year, 6 miles per
gallon would save up to $30,000 a year and the engine last twice as long. All
our new government vehicles should be CNG. Any local station that would be
reasonable in price could convert many of the newer government vehicles.
However $50,000 for a conversion seems high.
