This KSL.com article describes the CNG situation in Utah where supply has not been increased to meet the demand created by a enormous influx of CNG vehicles.

I am absolutely grateful to Questar for opening their stations to the public but I think it's obvious that a quadrupling of CNG dispensed over the last 18 months invalidates the following comment:
"'To go ahead and just start installing stations at every gasoline outlet we can find wouldn't be a prudent, wise investment of money for a service we're not sure will ever really respond,' Shepherd said."
Demand would suggest that something (child company / spin off / etc.) needs to be done to build and manage more CNG capacity in Utah.
