Exit Number or Street Name?

[sparker]

What I tend to do when giving directions that involve freeways is to refer to the street name when the recipient of those directions is local (and ostensibly has a working knowledge of the area) -- in other words, standard CA practice, as we were more than a bit late with exit numbering.  However, with out-of-towners who don't get to the region too often, I'll try to use both street names and exit numbers in order to cover all bases.  That approach seems to have worked out rather well!
