The article is pretty short, but the news is good.  UPS will expand its use of liquefied natural gas.  They currently use about 1.5 million gallons equivalents, and will be bumping it up another 500,000, or a solid 1/3 of what they currently use.  While it’s not huge, the more use of natural gas there is the better.  It’s cleaner than gasoline and produced in ridiculous amounts here in the States.
