Bless that woman's heart for surviving somehow, someway, both physically and (we hope) mentally.
I got my husband a GPS for Christmas a year ago. "Audrey" has saved us from some arguments over directions, but she has also tried to lead us astray multiple times. We got her updated quite recently, but she still has some "issues."
Last summer I knew the minute she wanted us to turn north to Kaibito that she trying to eventually take us up an 8-mile-long rough dirt back road (a track, really) on the Navajo Reservation to get us to Navajo National Monument (Arizona), when I knew there was a perfectly nice paved road a few miles further on. The paved road to the monument has been there for many years.
Also, some guys on our mountain bike forum went to
Big Bend Ranch State Park* (larger than Rhode Island!) to ride the
new trail system, which is really two-track ranch roads linked by new singletrack trails. They were navigating by viewing topo maps on their smart phones. The nice thing is that they could call the park rangers on their smart phones when they got lost close to dark with freezing temperatures on the way. They decided to back track to park headquarters and the kind rangers drove out to meet them, load up bikes, and bring them back. Otherwise, they had a great time.
