What have you done today with your Austin Seven

[Mick Hobday]

Robin,  yours is an inspired guess, but the A30 is not just off the A30 but just off the A40, which, incidentally, when I worked for Powys Highways very briefly in 1975/76 was to be redesignated the "Moscow to Cork International Route Number xyz123orwhatever" following some scatterbrained bureaucratic scheme.  That title had to be included on some realignment drawings at the time.  No doubt there's a global map of such routes somewhere.
