I once went around the world with a daysack. Just 3 pairs; socks, underwear, shirts and trousers (2 long, 1 short), 1 pair of shoes. In fact the camera, phone and solar charger was the only heavy thing.
I like the big outdoors in the countryside, but my limit is caravaning or camping... who remembers this...showing my age.... lol .... http://www.youtube.com/watch?v=3FJJ1Xd9ijs
