I have a chair with a hole in it that I move around my 11 acres. I put the dirty TP in a trash bag. I'm only there a few weeks a year so by the time I come back the waste has already gone back to the earth.

For water I fill up jugs in a local spring. The laundromat in town has showers for $5 and I'll use that every few days. I heat up water on my gas stove to clean up daily.

I'm glad you enjoyed the bike trip post. 250km is impressive! I think you're ready to traverse a continent! When I started on my trip the longest I'd ever ridden in a day was just under 100 km.
