Some American cities use buses, or trams, or trains. Peachtree City, Georgia, has a different solution: it's not quite public transit, but a hundred miles of golf cart tracks helps to keep cars off the road.

In the 1830s, two French brothers, François and Joseph Blanc, pulled off the first telecoms scam in history.

Back in the 1920s, wingwalking claimed lives. Daredevils would move around on the top of a plane's wings, in mid-flight, often without any harness or any safety line. Maybe they'd be able to clip onto something during takeoff and landing, but maybe not. There are still a few of those true daredevil wingwalkers out there in the world, but in the 21st century... it's usually a bit different.

On a rainy Scottish island called Jura, it's time to talk about the Manual, about long-term sustainable success, and about not having just that one catchphrase. The term "viral" has fallen out of fashion in the last few years, which is why this series wasn't called "going viral". And in truth, that's not what you want to do. Post Audio by Emi Paternostro, http://proximitysound.com Jimmy Cauty and Bill Drummond were better known as the KLF (or the Timelords, or the JAMs, or...). Their Manual is out of print, but I'm sure that won't stop enterprising people from tracking down versions of it, or footage of their burn.

The St Lawrence Burns were a series of deliberate fires in the soon-to-be-demolished village of Aultsville, Ontario, which was due to be flooded to make way for the St Lawrence Seaway. The results changed the way buildings are constructed around the world, and saved lives.

Rue Canusa (or Canusa Avenue) is a street that's split in two by a border: the northern part is in Stanstead, Canada, and the southern part is in Derby Line, USA — and border crossings here aren't as easy as they used to be.

It's been a long time since I've done a quiz or game show on this channel, but finally: introducing Lateral! Pull down this description for links to everyone's channels.

In Quebec, Canada, there's a town called Asbestos. It's an alarming name, one that conjures up images of lung disease and mesothelioma. So now that the town's asbestos mine, once the largest asbestos mine in the world, has closed... why haven't they changed the name? Dr Jessica van Horssen's book, "A Town Called Asbestos", was invaluable for my research. Its ISBN is 9780774828420, and it can be ordered from most libraries and bookstores. Her five-part YouTube series starts here: https://www.youtube.com/watch?v=e-66YqEHkzA The Story of Asbestos (1922): https://archive.org/details/0929StoryOfAsbestos According to Plan: The Story of Modern Sidewalls for the Homes of America (1952): https://archive.org/details/Accordin1952 The Gruen Transfer: How To Sell Asbestos, Canada: https://www.youtube.com/watch?v=KIpxelbkI0I USGS public domain microscopy of asbestos: https://usgsprobe.cr.usgs.gov/picts2.html The Canadian parliament quote is an official Hansard translation from the original French: http://www.collectionscanada.gc.ca/eppp-archive/100/201/301/hansard-f/35-2/153_97-04-10/153SM1E.html#9543 I'm at http://tomscott.com on Twitter at http://twitter.com/tomscott on Facebook at http://facebook.com/tomscott and on Snapchat and Instagram as tomscottgo

Over the North Atlantic, there's no radar coverage: so how do air traffic controllers keep planes safe? The answer, at least in part, can be found at Nav Canada's Gander Area Control Centre in Newfoundland. The North Atlantic Tracks are like freeway lanes in the sky, if freeway lanes were stacked a thousand feet on top of each other. More about Nav Canada and the tracks, and the new standards they're introducing: http://blog.navcanada.ca/increasing-operational-flexibility-north-atlantic/ Edited by Michelle Martin (@mrsmmartin) I'm at http://tomscott.com on Twitter at http://twitter.com/tomscott on Facebook at http://facebook.com/tomscott and on Snapchat and Instagram as tomscottgo

"_If you touch the👇black point then your whatsapp will hang_", says the message that's being sent around, and it's right. It's a text rendering bug, the same as many others -- which isn't interesting. But the characters it's using, Unicode RTL and LTR marks, are worth knowing about.

There's a concept called "Slow TV", championed by Norwegian broadcaster NRK, that emphasises long, unedited, contemplative journeys. Well, I've been snowed under with planning and editing some big projects, so for this week's video we're doing Slow TV with a video even less conventional than last week's. Thanks to Barry from My Virgin Kitchen - go see him cook and test three different garlic breads here: https://youtu.be/jYPYbIO9BLE - and to Steve from Random Aerospace, http://www.randomengineering.co.uk/Random_Aerospace/Welcome.html !
