Spiral staircase built around a 75' tree

A reader writes, "A man on Hornby Island, BC built a spiral staircase around a 75-foot cedar tree. He put a platform on the top to get a view of the ocean. This video shows what it's like to climb up and then down the staircase." LINK, Via: Youtube

The staircase has 99 stairs and goes up for about 75 feet (25 meters). He's built a platform at the top where you can sit and see mountains and the ocean.
