Nope, not the only one. I try to make sure that everything I use is usable over an open fire if needed, & always have a grab & go emergency bag. We keep dried food, waterproof matches, water purifying tablets, emergency blankets, fire starters, one of those foldable saws, a utility knife & utensils. That bag is kept with a hiking pack that has a copy of most of our important documents & a small tent.
My friends think I'm a total nutjob.
