I think I could write a number of pages on this switch over. Whats not to like about NatGas and its benefits to: air quality, to lower cost, to less maintenance.
I personally still see huge dump trucks on the road belching huge amounts of sickening black smoke out of their exhaust. Years ago the same applied to buses. That has gotten much better of late. Been to Disney lately? No problem, they got the memo.
Why not make our environment as clean as we can? Be all we can be!!!
