This is something I have always wanted to try, and I am certain it is possible.
I am about to start walking north to south through Portugal. The only things I intend to spend money on are tobacco, booze and emergencies. I am taking work materials (pens and sketch pad) and a single change of clothes as essentials. I will also buy a fishing rod (and tackle), a pot of dried chilis, bag of limes (I never use salt - lime juice is a very good alternative) and a cooking pot.
I have my laptop with shitty webcam for photos for fun.
My plan is to harvest as I walk and fish for fish in the evening. I am going to try living off the land 100% for food as I travel
I have fair knowledge for such a life but, expect (and, hope) to learn fucking shit loads as I go from local people who know best.
Camping out with no tent - proper vagabonding it
