I took a road trip from Washington, D.C. to upstate New York last weekend. Needless to say it took a couple fill-ups to get my old SUV through the journey.

A knowledge of gas taxes would have been incredibly useful.

On the way home, the gas light came on just north of Binghamton, New York, and I pulled over for a fill-up. If I’d had the Tax Foundation’s updated state gasoline tax rates map, I would have known better.
