Whoever says GPS units take the adventure away from your ride have absolutely no idea what they're talking about.
Anyone who doesn't agree with the directions...why the ****** would you blindly follow a computer's directions? If you see the hotel across the parking lot...GO THRU THE PARKING LOT!!! It's not trying to pull the wool over your eyes...it just doesn't recognize the parking lot as a legitimate thoroughfare since it's not a marked road.
I love using my Zumo...I've found more great roads and places while using it then without. Just ride along, make random turns, go thru random towns along the way...never without knowing exactly where you are. I still always carry paper maps for the big picture, but other than that, GPS has 'em beat.
And yes...I am quite proficient at reading maps and that skill will never deteriorate no matter how much I use the GPS.
