The other thing is, I think, that navigating the old fashion way is fun. We went cross country in the Olympic Mts. last year to the most lovely place where no one else ever goes. It was tricky. I didn't take my GPS or Forerunner so it was all map and compass and dead reckoning (r = d/t). Very rewarding. When my daughter was in basic in the Army she knew a little about navigating with map and compass and they thought she was a genius. Came in handy. Often does. Very rewarding.
