When I get anywhere near the Presidential Range, as I have recently on Isolation, I can smell the unmistakeable smell of coal smoke as I approach a summit ridge. Then as I sit on top gazing at Mt Washington I see great plumes of jet black smoke from the trains! How can we complain about pollution from the Ohio River Valley(rightly so) but feel it's ok to belch black coal smoke and cinders at the rate of a ton a trip. what happened to converting these things to natural gas? I know it's tradition here but so was draining old motor oil into the ground. Any thoughts?
