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?
As most people ~3 weeks.
I have 3 season camping gear so shelter wouldn’t be an issue. Water filter so that’s taken care of. The food will be an issue, European forests aren’t the best for foraging, I could probably catch some rabbit and get some mushrooms.
BUT as I don’t know nearly enough about wild food near me I will have to resort to experimentation and some poison would get me.
