If I had the gears I have now when I did my self-contained camping in my 30s, I'd have fuller use of my knees now. Alas, my previous touring female companions have found other partners. I enjoyed extended trips in northeastern US and up into Canada, three separate three week trips in France, and another two week one around the Peloponnese all cyclecamping. The one time we did a credit card tour in France, I found it to be not so much fun. Maybe that's just me.
But my current (and last!) wife isn't well suited to the details of self-contained travel, so even though I would like to again do cycle camping after I quit work, I'd have to enlist my old cycling buddy instead, who has done at least a long weekender this way. So there's hope.
