They really just don't work for me. I've been told a thousand times from the day I first started hiking as a teen in 1970s that walking sticks are the you-know-what, and I just can't make them work. You cannot use your binoculars, camera, etc. Your hands are taken up, and if you can't see (and for the artist/photographer in my soul photograph) then what's the point of the trip? I can walk for the sake of walking on a treadmill. I want to see/photograph the sights!!!
I haven't been able to figure out a solution to this problem. There have been occasions when the guide had to cut a walking stick for me where we stood but, unless I truly need it to get out of the rainforest alive, I'm still going to do without it because it's amazing how much it slows down your ability to get your binoculars up and running.
I have one very dominant hand and foot, the right. So I have to use the walking stick with my right hand. But if I have a walking stick in my hand, then my binoculars, cameras, etc. -- can't get to them in time. If I ever find I have become dependent on a walking stick, I'm going to fight it and try to see if I'm a candidate for knee replacement before I just give up and accept it. But that's just me.
