Hello Jan,
We use public loo's to empty our cassette toilet as well. What's the difference between doing that at home or when we're away?
It's quite surprising how one can find a public loo in out of the way places and offer the privacy to do so.
Yep, ditto we've used mountain streams to top up our water tank as well, try it in Switzerland the water is superb. We used to use a powdered drink called "rise and shine" with the mountain water and it was terrific. In them days we were always conscious of the weight we were carrying and were very into powdered products such as soup etc.
as it was always lighter than tins. Nowadays we always watch what different fats are in the dried products, my wife is in charge of that, for example, we don't use "pot noodles" as they have undesirable fat content.
With friendly greetings,
Draaiorgel. (Ian)
