Iowa Corn growers have hit the road to help summer travelers fill up with corn-fed beef and homegrown fuel.

The Iowa Corn-fed Summer Road Trip offers directions for travelers with flex-fuel vehicles to find fuel retailers offering E85 near the state’s best restaurants for corn-fed burgers and tenderloins. The map also includes some of Iowa’s summer corn-fed events, like the Iowa Corn 300 on July 8.

While gas prices are expected to hit four-year highs this summer, ethanol is helping to offset higher prices, and 10 percent ethanol blends (E10) alone could save consumers at least $39 billion this year, according to a Renewable Fuels Association analysis. The current Des Moines Terminal/Rack Prices are $2.16 for E10 and E85 is priced at $1.76 per gallon.
