PITTSBURGH—In an unprecedented encounter with a culture heretofore shrouded in mystery, Northco Logistics customer service specialist Ryan Barlow reportedly established historic contact Wednesday with the people who work on his office complex’s fourth floor. “I met this guy Kevin who said they’d been having the same problems with the air conditioner we’ve been having,” said the 28-year-old explorer in reference to the peaceful words of greeting he exchanged in the elevator with an inhabitant of QuestTech Learning Solutions, a meeting that to this point had been considered far too perilous to be undertaken. “He also said they had some leftover food and cake from his coworker’s birthday and that we could stop by if we wanted. He seemed very friendly.” Though admitting that no one had yet dared journey so far, the intrepid adventurer then regaled his colleagues with the legend of the remote and uncharted seventh floor, where there was rumored to exist a vast open layout and, according to lore, a ping-pong table.
