Meet the real "Solo man", extreme adventurer and aspiring documentary maker John Cantor.
Mr Cantor's latest challenge is an attempt to become the first Australian to cross the forbidding, grizzly bear-inhabited Brooks Range in northern Alaska.
He hopes it will be a case of "four times lucky" after his first three efforts ended in failure.
