Maps,,,, on a typical sunday I will head west for 100 miles,,, go south, or north, for 100 miles, head east for 100 miles, then head north, or south, for 100 miles. I usually come pretty close to home and NEVER look at a map. And I see all kinds of stuff I never imagined that were within 100 miles of home. Not to say that I don't want a GPS unit,,, I just don't want it on a sunday drive.
