I have not seen the show. But, when I lived in California, I had an earthquake stash, buried in the back yard. It had canned and dried foods, a shotgun (12ga.) ammo of mixed loads. solar and hand crank radio, solar panel to charge 12 vt batteries and a power inverter. clothing for all people in the house (vacuum packed. camping gear (enough for a normal camping trip, fishing gear. first aid kit and a wad of cash. enough to keep us in food water and shelter for a while if needed. buried in a locking PVC drum. Only I knew where it was buried. Every 2 or 3 years, I would open it up, swap out food, check conditions and reseal with fresh silicate gel packs. I also like the idea of a" trunk gun" that is there just in case of a wilderness breakdown, or escape convicts. I have seen both problems up close and personal. Lost a starter motor in the mountains of Flagstaff Arizona, in a blizzard no less, and had a prison break out west in the desert,, and were told by the highway Patrol to keep any guns loaded, and in easy reach, and do not stop for anyone, at any time, even if you were hit by another car. I also try to keep can goods and dried foods on hand in case of a short paycheck, or an unexpected expense. half gal. ice jugs in the freezer for coolers, can be drunk if needed (clean fresh water in clean jugs before freezing). Other than that, no. no escape routes, safe rooms, or dooms day kits. Just the Boy Scout's Motto....Be Prepared.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
