Wow! thanks for that guys, a rap on the Knuckles does sting a bit, but if you don't know or understand.....ask.
I can see your point & glad to be hearing from real bushwhackers.& I'm envious of the untamed wilderness you seem to have found in Britain......the UK does have some incredible " wild" places, the lakes, the beacons, yorkshire moors, dartmoor just to name a few, & I'll willingly drink the river water from these places, but I had in mind the water courses in more down to eath landscapes, those which pass through towns & agricultural land.....but if you say it's safe to drink, then it must be.
For a 2 nighter I carry 6 litres ( I have to carry my dog's supply too) & this is enough ( for me/us) summer or winter..Unfortunatly I can't do longer stints for the forseable future but if I did then I suppose I would have to resolve to drinking river water, radio-active or not.
Sorry for taking this thread away from it's original topic, I do tend to do that, but you guys are so damn interesting, I don't often get the chance to talk to "real people" about these things & I do like to " explore" a subject.
I am learning all the time & you guys have certainly taught me a thing or two.........................
