"I had a simple chore ahead of me. Travel to a handful of outlying remote offices delivering phone books. I like driving. However, this particular assignment set me against my most hated foe: suburban road designers. I swear, anyone who can't lay out a simple $#%*@$# grid pattern should not be in traffic management. Roundabouts, cul-de-sacs... God, save me from the suburbs." [Source: Diaryland.com]

There are also many roads that do not have the names posted."
