A Trion station at Hollywood Way and Magnolia Blvd. in Burbank, CA.
This station used to be a Unocal 76 and the owners went so far as to
duplicate the globe with one of their own (albeit a bit smaller in size.)
Three drops of oil make up the trion. It was not revolving when I saw it,
but maybe they can turn it on to do so.
