Our very own Alex Ng, a long-time web developer and general tech guru, recently completed a 116-story high walk around the CN Tower in downtown Toronto—and he wasn’t even fazed. The CN Tower’s EdgeWalk is in a class of its own, recently having been awarded a Guinness World Record for the highest external walk with no railing on a building in the world. Although he admits it was a fun experience, he adds with a chuckle that it wasn’t his idea either.
