Sure, np. Here's a story you might enjoy. Years after 9/11 I was working with a group on the design for the new World Trade Center rebuild fiasco, and was part of a group inspecting the abandoned subway tunnel in the immediate area under and off to the side of the twin towers. We were escorted by an uptight guard that commanded with a loud voice that we were to obey his commands at all times. The group of maybe 20 engineers/architects/designers walked down the dimly-lit tunnel (of which there was nothing to see - an undamaged old subway tunnel). About dead middle of the 9/11 site and off to the side of the main tunnel there was a smaller tunnel (an old walkway obviously) that went about ten feet off the main tunnel and was opened to the outside. As part of the inspection a few of us went down that side tunnel and briefly glanced out the doorway. Our escort/guard went ballistic and almost stopped our inspection because we had glanced outside without asking his permission. Obviously, he didn't want us to see out the doorway - to this day, I wonder why.
