It's a great feeling to have the outdoors around you as a bathroom. The light is nice and even, the wind is fresh, the smells are green, and it feels like you're one with it. If it's windy, your lather may dry a little, though.
This picture was taken at my parents earlier this year. I put a nail on a tree to hang a mirror, another for my strop, and I was good to go. This tree is sadly dead, but I planted it 20 years ago as a sapling. It lived long enough to give me shade, and let me shave.
