A stroll on top of the CN Tower restaurant in Toronto. What a high.

Here’s one Guinness World Record you can match without having to lift a table with your teeth or live with scorpions for more than a month: Walk outside on top of the CN Tower restaurant, 116 stories high, to match the record for “highest external walk on a building” set in 2011. Here’s my Washington Post story about doing the Edgewalk during a June visit to Toronto. Photo credit: CNTower
