70 versus 80

Letter to the editor

I read in Consumer Reports that research done on a Nissan Altima and the Toyota RAV 4 that reducing driving speed from 65 to 55 miles per hour gas mileage increased 6 mpg in the Altima and 8 in the Toyota RAV 4.  

I was thinking if South Dakota wanted to reduce the carbon we are putting into the atmosphere, we can reduce the state speed limit from 80 to 70 such as our Minnesota neighbors have.

On the other hand, if we are a bunch of climate change deniers, we probably could care less about what kind of world we leave to our children and grandchildren.
