We actually have three levels of names. What EVERYBODY refers
to as the "Fairfax Count Parkway" is also known as state road
7100 and by the official name "John (Jack) Herrity Parkway"
(it also has a fourth name "Springfield Bypass" but they gave
up on that one some time ago, the road still fails to either
enter or bypass Springfield, that's the last two miles they
ever finished).

Margy's car's satnav system displays the first three of those.
It makes the screen a bit cluttered.
