Ever want to explore the underside of the infrastructure of the greatest city in the world without, y'know, going down there? Got half an hour? Last summer Andrew Wonder and Steve Duncan went on a tour of the city's less visited attractions with trips to the abandoned City Hall station, New York's first sewer on Canal Street and the Lincoln tunnel and the results have just come online. So sit back at your desk and go vicariously run from trains while avoiding the third rail! Spot century-old footprints underground! Meet the nice folks you find down there! Climb a tower of the Williamsburg Bridge! All without actually going anywhere.

That video was shot last summer, but Duncan hasn't stopped exploring. Along with explorer Erling Kagge, Duncan recently went and spent five days underground with a Times reporter. You can learn more here.

Also? Don't do this at home kids.
