And propane heaters.
You can bring a lot in a car, can't you?
Still, for a hiking list, I think
this list does OK for the Kim's car trip. A map and a PLB are pretty good things to have along.
Which brings us to the most important part of what you bring with you: Your brain.
Absent one's brain, there's very little that any list can do to help.
Thanks for all your good comments,
