Vacation season has been in full swing and Americans are on the road. Gasoline has not been $4 a gallon, as people feared it would be back in February when oil was above $100 a barrel. You can pull your fifth wheel into the campground, take that new boat for a spin on a smooth-as-glass lake in Maine, spot American eagles while on a cruise in Alaska. These are the fruits of a healthy oil and gas industry. No prohibitive prices. No fuel shortages.

Maybe it is a good thing ...
