Purely the human-powered sort is what I have in mind. Does anyone use some type of frame with a couple of wheels to take the load off? I am asking because I discovered recently that I will be punished by days of lower back pain if I carry more than a couple of pounds. I’m not into pack animals of any kind and I’m too stubborn to give up activating, so wheels it must be.
Since I’m already age-limited to fairly short hikes up a few summits with good access, a wagon or cart wouldn’t cramp my style at all. The question is, must I invent the wheel (so to speak) or has someone already explored the options and found a workable solution?
