It might sound a little over-enthusiastic, but do not neglect what getting stranded in the middle of the woods or of the desert might represent. Chances are wherever you get in trouble, cellphone reception will be down to -3 bars—that won’t be the time to think of that stuff you “should have brought”. Be prepared. Bring tools, parts, an extra jerrycan, a tire patching kit, etc. It’s best to be over prepared than not enough. It might sound obvious, but you’d be surprised at the number of stranded people who could use a little extra fuel you can come across on your journey.
