The enactment of the ordinance prohibiting idling vehicles was a bold move and may just be another darn law, but we need to realize that one gallon of gas weighs roughly the same as a gallon of water, about 6 pounds. When it combusts, the carbon breaks bonds, expansion of gases occur, along with heat. The total weight left over is identical to the starting weight. Nothing is lost, just changed. Therefore, if you get 26 mpg, you are depositing about one pound wherever you go in that mile. Every pound of petroleum drilled ever since the beginning of time is still here on the planet in either light gas up in the stratosphere or heavy oils close to the ground.
Valleys are very prone to inversions. Many times it is warmer at the top of Baldy, more than half a mile vertically, than it is in downtown Ketchum. While living in Eugene, Ore., during an inversion, I once saw wood smoke come out of a chimney, go down the roof and end up on the street.
Next time you are in Twin Falls, look at the stained horizon. Then when you get back, see how beautiful the blue is at the point that it meets the pure white snow. Do you want to compromise that?
