hello,
It's been of interest so far & some valid points made in reply. On water purification I would have thought there would have been some method of boiling water taught to them, although they did say something about a DVD & manual training beforehand? I could think of a few methods minus a set of billy cans etc.. keeping in line with the historic timeline of events. I agree with you "As entertainment it is ok but as an historical or archaeological experiment then it's a bit naff" delboy so hopefully once the Instructor goes, it's down to some proper Bushcraft. Say's he when they pull out a SAK or a Leatherman then start squabbling over a Gränsfors Bruk axe v flint head tools?
Regards
David
