stove is a ultencil holder hobo brought for a quid from a pound shop, the same for the tiffin tin set as pots and pans, cutlery and serving ultencil .
boots are either wellies or work boots either cost a tenner from the markets
ok so we dont have ventile clothes or cheap and nasty gortex and hand crafted leather boots or a knife so expensive a normal person would never take it out the house in case they lost it or blunted it.
but i go to the allotment and the woods and enjoy myself, i still cant do fire by friction lol and i hate waking up cold, but i can still enjoy myself when i want and one day i will be able to identify more than a few trees and plants maybe even get it up to a hundred names.
you never know one day i might even identify and pick and eat a mushroom from the wild rather than spending ages studying it and then walking away from it!
