Are you absolutely sure about that? Per passenger mile on a modern full
aircraft?
exactly. you should try walking a track that's been used by horses. My
god they make a muddy mess of anything. Worse than 4x4s.
I'd have to disagree. I used to ride on a lot of logging tracks. The
problem is that even tractors dig wheel ruts which get dug progressively
deeper at sticking points, whether or not there is initially a lot of
mud. And on stony ground horses actually help, they break up the larger
stuff and compact the surface into a mixed-size surface which is both
firm and well draining, whereas vehicles with driven wheels just dig
holes through wheelspin.
I could show you a track which walkers never used, it was just very
unfriendly scree. After I had been riding it twice a week for ten years,
it became very nice to walk or ride on, and other people started to use it.
