Hmmm... I concentrated my list on winter warmth and sustenance.

Seems to me that in regard to the car, eliminating the need for "Search" rests mostly with the computer on my shoulders that God provided.

Augmented by maps, compass and GPS.

And, in the winter, tire chains and shovel.

No one's had to search for me yet. Knock on wood....

If I needed to be found, then I've got multiple means to make fire, mirrors galore to flash a signal, a strobe light and a large blaze orange "HELP" flag that I recently found on sale.
