5 years later, gasoline is finally as cheap as CNG (for now)

All the poor folks that have suffered with $3 and $4 gasoline prices of the past five years are now experiencing the thrill I've had for five years of filling up with $1.66 fuel.  

Imagine how I felt when the fuel price was $0.66, $0.75, $0.89, and $1.25 for my Honda Civic....

Yes, the CNG Honda Civic has paid off it's $2,500 extra purchase costs with the vast delta between gasoline and CNG prices over the past five years. 

CNG in Oklahoma has been less than $1.80 over the past five years - and based on the abundance of natural gas, I expect CNG to continue to be $1.50 to $1.80 for many years to come.  Can you say the same thing about gasoline prices?
