The shortest distance between two points is a straight line. But when that line is nearly a thousand feet off the ground and no wider than the head of a pin, it's a sight to behold.

Earlier this month, Spencer Seabrooke trekked to British Columbia, Canada where he set a world record for longest free solo slackline when he walked 210 feet between mountains 950 feet above ground with no safety equipment on him.

In other words, this was extreme, dangerous and extremely dangerous.

Seabrooke nearly takes a spill in the beginning of his walk. You'll know it when you see it and realize you're holding your breath. But he recovers nicely to finish the exhilarating adventure.

Seabrooke's accomplishment was so impressive that it puts Nik Wallenda's latest feat to shame. He set out on his longest walk -- 1,576 feet -- at the Wisconsin State Fair earlier this week. Check him out in action below:
