I'm a mapper. I have drawers of them, books of them. Maps or Atlas' are within arms reach of most places that I sit in the house. I enjoy planning trips. I have favorite roads, but I try to use every alternative road possible on my motorcycle rides. I have had my GPS for over a year and have used it as an aid on trips, nothing more. I visited my brother in SC last weekend. I've been there several times, but always in the cage, so Interstate highways were the route. This time I put his address in my Garmin and selected "fastest route" with highway avoidance enabled and took off. I put all my trust in the GPS No map for back up. It was a cloudy day and by the time I was 50 miles from home, I had no idea where I was going, but I did what the screen showed. I made it to his house in the time it said I would, and the miles it estimated was spot on (311 on my odo./306 on the gps, about the same % difference as mph discrepancy between the speedo/gps). The GPS took me down roads I never would have picked on a map, if they even showed on a map. Several times I had to stop and use the zoom to reassure myself that I was ok. On the way home, I selected "shortest distance" and it took me on a totally different route (still good). I think I'll still use maps so I get the "warm fuzzy" feeling of knowing where I am, but the gps will be on standby.
