There are backyard summer sports, and then there are crazy, life-risking sports. Spencer Seabrooke apparently enjoys the latter.

Check out this stunning video of Seabrooke breaking a world record slack line walk in beatiful British Columbia. Seabrooke does this incredible feat between two cliffs in Squamish, BC. Watch it twice, first for the crazy slack line action and second for the awesome scenery.
