It"s Swiss National Day, and the citizens of Switzerland are taking the day off. They’re celebrating the 1291 confederation of regional cantons that led to the formation of their country. The nation first celebrated this milestone 600 years later, in 1891, but the day wasn’t declared an official holiday until 1994. Perhaps the Swiss are able to summon that level of patience as they cross the Charles Kuonen Suspension Bridge in the Alps near the village of Randa. At 1,621 feet, the bridge is currently ranked the world’s longest pedestrian suspension bridge. It’s also pretty high–at one point along the span, brave crossers are 279 feet above the ground. Just keep moving forward and maybe yodel a bit to distract yourself…
