Ever notice there are far more web sites on survival in the woods (I don't mean millitia or rambo or guntwit stuff). I'm talking how to find food, shelter, first aid, orentation, etc...
That should give guntwit a hint. If you can't find shelter or food or water then the gun means nothing. If you can't find you way around then your gun means nothing.
Every year handfulls of people survive being lost in wilderness, ships sinking (I'm sure that 11" POS CAR would be just 'vital' on a sinking shrimp boat), plane crashes, cars breaking down in the desert, or in winter, etc... but no, guntwit 'thinks' skills in these areas will just pop up in his head.
