Why does this happen so often on the left coast?

I work at a land-management agency and I am occasionally asked for directions to campsites or back-country areas. Many people I talk to seem to have no navigation or map skills, or even rudimentary sense of direction.

They usually want me to just give them an address to plug into their GPS. I have to explain to them that campgrounds deep in the forest don't receive mail so they don't have an address.
