I usually backpack a month or more during the summer, and use trekking poles every step of the way. Reinhold Messner used them on his solo climbs of Everest, and they have been popular ever since. I haven't used them hunting yet, but as I get older, it might be as good a reason as any to switch to a longbow, which, properly padded on the tip, could function as one of my trekking poles. I could string it quickly using the push-pull method and carry an arrow in one of those single arrow holders that attaches to the limbs.
