I have watched several of these episodes and in 3 of them the guys wimped out, leaving the woman alone and these women all made it. I don't consider myself a survivalist, nor do I have any formal survivalist training, but I do think I have a good amount of common sense. In the programs I watched, the producers provided either a machete or fire starter, but not both and each contestant could then choose one item. I have seen people bring duct tape, fishing line, magnifying glass, parachute cord and a cooking pot. Basically you and your partner are going to end up with three items. I have never seen anyone choose a waterproof tarp, which would be my choice after a machete. It will provide instant shelter and warmth. Seems to me like the biggest problem they have is being cold. Making a fire is a poor way to try and keep warm outdoors. Even my fireplace doesn't work that well unless you are sitting near it, and this is indoors.
My three choices would be: 1. Machete. 2. Waterproof tarp. 3. Windproof butane lighter instead of a fire starter.
For you survivalist types, would I be making a big mistake taking a tarp instead of some other item?
