Funny thing I have found about men, women and maps/directions:
Men can read a map and go anywhere but have a terrible time with directions. Women can follow directions anywhere but can't use a map to save their life. My wife has been known to have the map upsidedown (that'll really get you lost!). Generally, it's best if I consult a map myself and perhaps highlight the route if wife is going to be navigating for me. We used to try to do the hare-and-hound rallyes the local car club put on. Had to give it up. Better that than divorce. Still, I would not mind getting a bit lost if I was traveling the beautiful countryside you were just crossing. Wife and I like to take long rides out in the surrounding counties looking for older (pre 1900) homes. Great way to enjoy the SL on a warm day.
