Spending two weeks in the open air surrounded by trees gets you thinking. What must it have been like to live there all the time like a lot of our predecesors did, not so many generations ago. Life must have been a lot simpler and more in harmony with nature. There are still forests that we can visit, but living, working and sleeping in the forest is something else. For one thing, there is a lot of food growing and living there. The number and variety of mushrooms growing is amazing and there are a whole lot of nuts and root veggies to eat. When the crash comes, the forest is the place to head for. The air is very good, I would recommend anyone suffering from asthma to go and sample it for a few days. People knew about the things that live and grow in the forest and being clever types developed skills to harvest the good things without destroying them. Coppicing Birch and Hazel are a couple of ways this was done.
I did a sketch of a neat little way of using woodcraft to store the sweet chestnut logs which I think is a good example of 'bodging' - working with the raw materials in the forest.
Another thing I recommend is running along woodland tracks... wonderful.
