Why would Zions National Park go backwards in their progress for clean air? for almost a 1/4 century Zions has been running its shuttles on Clean Propane. This year the park has received $33,000,000.00 to replace its 20 propane buses with new Coal Burning Electric buses. Why would US tax payers allow the government to spend a massive amount of money on a bus that gets its power from coal? Why would we want to produce more emissions and spend more money? Who are the people profiting from a bus that cost 10X the amount of a propane bus?
