The impossible

I love my mountain bike riding but there hasn't been very many stories about it even though it has so much to tell. for example riding by your self and going over a jump that you where not expecting at all to land and smash the whole top end of your femur and being stuck in the bush for 6 or 7 hours before someone on a quad bike found him in the middle of nowhere. anyways that was my dad. but what if bike was the only way home and the was a massive creator that you had to get across. either way there was no way around it. so the guy quickly builds a jump and tries to get across. he doesnt get enough speed and falls but as he is falling he lands on a old ramp/board walk that is about 20 cm wide and jumps from board walk to board walk at a very high speed till he finally reaches the other side. only to find he left his helmet on the other side of the creator.
