Maps and a compass do not fail. The kids still chuckle at my stack of maps carried in the glove box.
And I also always have a Sat phone - since there are areas with no or extremely weak cell coverage.
The family claims she doesn't have any problems. Hmm, better have her re-evaluated. It takes some kind of stupid to pull off what she did.
Agree with carrying maps. I have a box full of county maps that show every little back road. Made up boxes for the kids when they left home. The first time their cell phones quit working, what then? GPS around here always points you in the direction of water.
