Ok, here's a question I have.
In the future when I finally commit to an attempt on the AT, I would like to do the "In and Out" approach to towns. Not because of money, or trying to preserve the "Wilderness Experience", but simply that I enjoy being out in the fresh air, and don't sleep on a bed even at home. Of course the odd time may come up where I want to stay in town for whatever reason, but for the most part I would like to stick to shelters and camping.
The catch is I'll need to bathe once or twice a week. What have people done in the past?
