I started reading your post last night and im only at the half of page 2 but its really interesting. I have 2 questions though: You said its not respectful so shit in a boxcar but what if your on a long trip, the train is going fast and you really have to shit?
My second question is do you build a small shelter with trees for when it rains or you just dont care about getting wet all night long, or for a week long?
