Sometimes, maps are better than GPS

You can get the surprise of your life when you use an online-mapping service such as Google Maps or Mapquest.
When I punched start and end points into Google Maps for a trip last week near Yosemite, the suggested route included a Jeep trail that was built in 1916-17 to 1913 wagon-trail standards, has been closed to traffic since 1938, and now sits in designated wilderness open only to hikers and horses.
Heh, heh, heh. Good thing we knew better. Still, it's hard to believe a service that millions rely on could be so far off.
