We have a GPS. And a road atlas, and when we travel we take state maps that are applicable. It's amazing at how inefficient a GPS can actually be.
Driving back from Holden Beach on Monday, traffic on I40 was stopped close to Hwy 42. We whipped out the NC roadmap, and made our way back on back roads. GPS kept trying to redirect on major roads.
While I like GPS, I am a visual guy, so I really like balancing what Garmie (our kid's name for GPS) against a map.
