I realize that the people making the biggest fuss in Durango are probably new commers maybe from areas where coal smoke is unknown. But at the same time those of us that have grown up in areas where coal was used to heat buildings and homes, would probably see the relativity of the amount of smoke produced by the rr. When we visited our many Colorado aunts, uncles and cousins when I was a kid in the 60's some of my relatives still did not have electricity and were both heating and cooking with coal. Imagine what it was like when nearly everybody used coal in Durango for heating and cooking! The town here in N.E. Ore. where I live and grew up used to fill with inversions of coal smoke as nearly every business building was stoked up about the time I was walking to school. My dads store burned coal and that was one of my tasks as a kid to tend the stoker and haul out the clinkers. Coal smoke was a given and most people didn't seem to mind that I can recall. I have not been to Durango since 1968, but I believe my observation is valid that the @#$%& are complaining about air quality that is vastly improved today from what it was like in many cities only 30 years ago. Frankly I miss the smell of coal smoke!!
