Dec. 27, 2017 - As a teenager, Bob Thissen rummaged through abandoned buildings for fun. About 11 years ago, he decided to go pro with his intrepid interest. Today, Thissen is the 32-year-old filmmaker behind the YouTube channel Exploring the Unbeaten Path, where he's upgraded from investigating urban sites with only his curiosity to now having a drone, cameras, and a microphone, too. Thissen is an urban explorer, a subculture of people who explore manmade spots that, for one reason or another, have been abandoned and left to decay. He has visited hundreds of locales, including more than 50 countries on four continents. From soviet space shuttles to disaster-stricken cities, take a look at some of his favorite adventures from the year.
