If the fellows from the "WV Department of Tax and Revenue, Criminal Investigation Division" happen to stop you and dip your tanks, the 5000 dollar fine makes off road very hard on your wallet.

There is only about a 30 cent difference in price most places.
16,666 gallons of fuel would make up for the fine at that rate. and another 533 would offset the court costs.

I average getting checked about 3 times a year.
