Forget your umbrella and boots? No problem
Making your way through a futuristic tunnel or walking high above the ground in an enclosed walkway sounds like something out of science fiction, but these tunnels and skywalks are just a simple acknowledgement that weather can be complicated.
These enclosures are usually built to keep people comfortable despite the outside temperature. The most expansive climate-controlled pedestrian networks are in places with cold winters, like Calgary, or hot summers, like Houston. Most are located in downtown areas where workers welcome the chance to grab lunch without donning thermal underwear or arriving at an appointment without having to change a sweat-soaked shirt. This is a segment of Toronto's PATH system above.
