On Thursday, I filled the tank for $4.09, which was about 10 cents less than the other gas stations in the area. I think the prices have come down a bit, and they're going to come down more if the Maryland "gas tax holiday" gets enacted. It seems sort of silly for me, as the state gas tax is about 30 cents a gallon, which means that one would only get a $3.00 savings a 10-gallon fill-up, which is a ~$35 purchase. And all that tax money that helps maintain and build roads and transit is forgone. The better thing would have been to give a gas tax credit to people below a certain income for whom the increased gas prices really are a financial burden. The rest of us can afford to suck it up and pay the extra $3.00.
By the way, this was the first time I had paid over $4.00 a gallon since 2008, when I was in Alpine, Texas, and had to fill up my tank after my visit to Big Bend National Park. Gas was pretty cheap in San Antonio, but not in Alpine, which I guess is at the end of the supply chain.
