This recent posting popped up in my YouTube dogpile. Enjoy it for the journey. I was thoroughly intrigued. (Whether you are or not, and what perambulations this sort of thing leads to in your mind is your own affair.)
TL;DW: Four retired old farts decided to rig bicycle contraptions to allow them to travel across mostly wilderness Patagonia for several hundred miles along the antiquated and largely abandoned small-gauge railroad line running near the foot of the Andes in the southwest of Argentina.
I'm glad they had fun.
Can't believe none of them thought to learn a little Español prior to the undertaking, even a bare smattering, but that's some people for you. And with the tiniest pushing, they could just as easily have turned this travelogue into a full-fledged NatGeo episode and gotten paid to do the whole thing.
It would have been no less epic, and twice as enjoyable.
Maybe that thought will occur to them, and they can make it a twice-in-a-lifetime experience, and even more enjoyable for us internet gawkers.
Contrast that charming trip through a rural region of a Latin country, with the fate of the tofu-slurping Birkenstock-wearing buy-the-world-a-Coke millennial snowflakes who recently got shredded and diced by jihadi @$$holes in Muslim Tajikistan.
There are places in the world you can do this sort of thing in your twilight years, and others where you'd be a fool to try.
I've never been much for tourism, but were the bug to bite, this strikes me as far more interesting than gallivanting around with a bunch of fat old cityfolk in their declining years, waddling from tour bus to museum to buffet to hotel.
In fact, I'm already building the cargo-capable four-wheeled recumbent bike with adjustable-width frame in my head, for just such a thing.
A couple of tips from other world travelers I've always remembered:
Learn a little bit of the language.
Carry a deflated soccer ball or three, a hand pump, and a small jarful of inflation needles, and you'll never lack for local friends between the ages of 5 and 35.
