You can pump your own in parts of Oregon now

Oregon is a big strange but some would argue that your ultimate gas price is determined by the distributors and tax authorities and not by the minimum wage earned by gas attendants --- goes against the basic econ rules we learned 40+ years ago but "free market" ain't so free when there are limited number of distributors.

Oregon laws remain in effect because everytime someone tries to overturn the the law people point out that the gas in nearby states is usually higher than Oregon.
