But I have met people for whom a road map is like reading ancient Greek. They have no ability to translate
LOL, I used to use maps! Started with Rand McNally. I used to sit and spend hours reading maps in the thick 50 states Map books, well before I even had a license or knew how to drive. As for GPS taking the fun out of travel? Not if you have a Garmin or other REAL Gps. Not these phone based navigationals. With my GPS, I've been able to safely navigate so many cities by car. I had got tired of getting lost, being late, and almost causing accidents by reading maps.
GPS also helps avoid traffic, allows you to take (or avoid) the 'unpaved' roads (once drove 35 miles on unpaved road in Montana), and it just allows you to select different routes to take on your journey. So now, I absolutely don't agree. I think it enhances it, and makes it safer. Maps are good for surveying a state/region before you travel, but you use the GPS to get you there.
...And I NEVER use the GPS voice either. If I do, I make it talk in foreign language just for laughs.
