At christmas time last year I had to recall my knowledge learned from watching and episode of bush mechanics a few years ago.
A flat rear tyre on my XR200 trail bike was not gonna stop us getting back.
A tyre stuffed with coconut tree leaves works just as well as the bush mechanics long grass trick.
Rode for over 1 hour carrying 2 of us across Calicoan Island to Guiuan in The Philippines till we reached a vulcanizer to fix it up.
