Did I hear cheap, easy to fab saw carry rig for the backcountry? Doesn't get any easier......
Military pack board, a few pieces of scrap 1x3, a bit of 4" PVC, some webbing, a few screws and about twenty minutes.......... Done. I doubt I've got more than $7 bucks into it. You could probably do the same thing with an old external frame pack, I usually see them for less than $10 at garage sales all summer long. I've used a wildfire saw pack too, but they are pricey for the casual user and I don't care for the bar up position if I can help it. I do the shoulder carry with a carefully padded saw for short duration but if you gotta hump it far in difficult terrain where both hands may be needed.............
That bike pack looked interesting, but have yet to find one on a rack somewhere......or even a shop that could get their hands on it. Somethings I'll buy over the web, backpacks, boots and technical stuff that I can't put my hands on aren't on that list.
