Was it Bigfoot? Scary night after motorbike broke down on remote trail. Not this track or my DR650.

Experienced motorbike rider heads out on a dirt road on his DR650 to recall the scariest night of his life which occurred many years before on a different remote trail as a teenager when his 1974 two stroke Suzuki TS185 broke down in the wilderness many miles from the nearest human being. Was it an encounter with a Bigfoot or what we in Australia call a Yowie?
