Well, I should probably start a separate topic on this, but where I
live most bus terminals have no name and the public administration
reports general descriptive directions (such as "downtown" and
"suburb"). Does that mean that from and to should be blank on those
relations? Or should the local community make up fictitious names for
the nameless terminals?
