I came across a guy trying to tow out a bogged down tractor when I was touring in foreign parts. There was a bit of a language problem, but he wanted me to drive the 'stuck' tractor, the one that had its back wheels hanging over a 5 metre drop and was rather light on the steering
!
I signalled my agreement to help, but only on condition I drove the towing vehicle, and he drove the stuck one.
We managed to get both tractors back on the road and after much gratitude was expressed in sign language I went on my way.
Just another everyday tale of cycle touring.
