Very sad news indeed.
Wheeling alone is not a death sentence uless you are not prepared for the worst.
I have wheeled alone many times, but always planned for the worst. You may need to spend days in blistering heat or extreem cold, and possible injury.
I know many people that wheel alone, but they too are prepared.
It's important to be prepared for the worst even if you are with a group. Groups get stuck too, or you could get separated from them.
Walking out in his situation was one of several options. Obviously he was not prepared for it. Staying wiith your vehicle is the best option if somebody knows you are supposed to be home on a certain day.
Not only is your vehicle easier to spot, but it is a wealth of survival equipment and signaling sources.
Burning your spare tire will attract attention from the plume of black smoke, as well as warmth.
Think before you hit the trail, even with friends. What if your wheeling buddy drives off a cliff and dies, and your vehicle is stuck? What would you do? Are you familiar with the entire area you are wheeling in? Could you survive with your family indefinately? Can you protect yourself from predators? Everything.
Check your survival supplies in your Jeep. Make it all small and efficient, and portable.
Prayers go out to the family. RIP.
Betcha' wish your girlfriend was as dirty as my Jeep!
Zombies hate fast food.
Hang on! This is gunna' be a thrill ride of geriatric proportion!
