Should I get into all the gory details about biological and sanitary needs when you are on a pilgrimage? Maybe I should just mention that it is a good idea to bring toilet paper and a small shovel, for two distinct ways of meeting the need. Usually, where you'll need the shovel there will be enough moss and foliage that you won't need toilet paper, and where you'll need toilet paper there won't be a need for a shovel.
And you should bring soap. That part should be obvious.
Your digestion will not always wait for you to find the perfect spot. In some cases, you will wake up in the middle of the night and find yourself sleeping on a patch of grass behind a gas station, and find it necessary to put on your shoes and get your flashlight and find a patch of trees or bushes as makeshift sanitation.
I managed to fall asleep again after this incident, but not for long. I was irreversably awake long before the day was dawning. I decided to keep walking.
The first thing I noticed was that I had crushed a slug in my sleep. When you sleep outside in some places, you may notice that slugs crawl onto your shoes and sleeping bag and backpack during the night. I'm not sure what they're looking for that they can't find in the grass.
This one had come all the way to where it was right next to my head, and I must have turned around in my sleep right around then. Fortunately it got stuck between my hat and the sleeping bag, rather than getting crushed into my actual hair.
Still, it was gross. It had been one of those big brown slugs, a bit like the lower lip of a large African woman. And it was now a gooey paste on my hat and my sleeping bag.
I packed my things and started walking. I had walked at night before, and had walked through fog almost every day, but this was the first time I was walking through a foggy night. Here and there a dog barked, but otherwise the tapping sound of my walking stick and my heavy breathing were the only sounds I could hear. The street was not illuminated, and there were sometimes large stretches in which there was no house or any other source of light. I had to use my flashlight sometimes, or just walk through the misty darkness.
I took a break after half an hour to stretch. I had heard that it is better to stretch after warming up than to stretch cold before exercising.
