You just get the idea you need to be in the wilderness (whatever is local - hot, cold, dry, wet, etc). You can pick anything up you want on the way out, but you can’t stop walking out the door.
How long do you reckon you would make it living off the land? Any special circumstances or tools that would have helped?
I live next to a major city and way in the midst of the metropolitan area so I could survive pretty long given I would likely be arrested within a day or so.
