I accidentally found this interesting place some time ago while I was in a cab from somewhere back to my office. The walkway in the picture is no different from any others but it is made uncommon by its location. It cuts through a network of underground service lines including dangerous ones such as high voltage cables and gas pipes. Walking along this walkway probably gives you a chill down the spine like walking through a guaranteed safe path on a battlefield filled with landmines. Stepping out of it and then, boom!, you are gone.
