I went camping this past weekend. When I don't sleep well (i.e. anytime I'm not in my own bed at home), I always have to get up in the middle of the night to go to the bathroom. The outhouse was a significant distance from my tent, the washroom even further.
So I took a bucket, with a lid, and set it up in the vestibule of my tent to use as a chamber pot! The gross part comes in from having to empty it...
What a fantastic idea - I'm so glad I did that. So instead of being awake from 5-6 am on, I got to go back to sleep until 7-7:30!
And then, when we were leaving, I used the bucket to put some wild leeks in to take home and plant in my garden. So it was a leak/leek bucket.
