Wax on wax off...isn't that Barbour-Ryu.
As for aims and purposes...
Eight years on, and this is still the best description out there that I have seen.
I don't mean any offence here, but an older practitioner seeing that standards are slipping, the young are all about gadgets, not about learning skills, etc, well, I think that coming to see things that way is all but mandatory as you get older, and I am sure that people in their 70s were saying the same sort of thing in the 1960s!
I don't "do bushcraft" either, I just like to travel, camp, hunt, fish and make things that use skills that fall within the centre overlap of that Venn diagram. I think the number of people who go as far as Keith has done have always been a rare minority, rarer still that they stick at it for so long. In years past one might meet such people in person at events, but that was hit and miss. Now with the internet there is greater visibility and accessibility, lots of people who just dabble here and there. There are still people who practice a lot of skills, but a lot of them do not post on forums, do not make videos, and with all the noise from those that do, they are easy to overlook.
