 A texter writes that in North Dakota, it's $50. If you park your dirty vehicle in a recharging station, it's a $50 fine, apparently. So are you willing to part with 50 bucks to make a political statement? A texter writes, I could see in limiting parking people would park. They're there because it's only in a good spot. A texter writes, I run used waste oil and vegetable oil in my old diesel pickup. How's that for dirty fuel?
