Back in the mid-1970s I joined the staff of an outdoor education course where the culminating activity was a 6 day canoe trip. At that time, other than the Grumman canoes, everything was traditional; including real Duluth packs. I'm not sure how it happened but I ended up becoming the instructor for how to set up a wannigan with a tump line in what we called "Campcraft." Long story short, there were a lot of horrified gasps when students first saw the wannigan but eventually, when the finallly learned how to tie the tump, it all became clearer to them. While I won't say they all "loved" using one, they certainly understood the value of the system.
Funny thing; now, many years later I still use a tump line when tying my bedroll for living history programs. It's amazing to me how that skill of tying it never left me. So happy to have been able to retain that bit of knowledge.
That's all for now. Take care and until next time...be well.
