This Guy Riding A Unicycle Along A Tiny Ridge Will Give You Extreme Vertigo

    Do not try this on your own.

    This is J.D. Guignard, a daredevil from Saskatchewan.

    And this is Castle Butte, a 60-metre-high rock formation in Saskatchewan's Big Muddy Valley.

    At its peak, Castle Butte is only about a metre wide, with a long and dangerous drop to either side. So, naturally, Guignard rode a unicycle on top of the butte.

    Here's what it looked like from his perspective.

    Here's the full video of Guignard's stunt.
