I work at a college and have an office. I go in through a side entrance to my building and rarely ever see security. Yesterday, a guard happened to be passing through the area when I was rolling my Swift in, as I rarely fold it at the office. After holding the door for me, he said "you can't have a bike in the building." I pulled the seat post up and kicked the triangle in and in less than 5 seconds said "It's a folder." He said "okay - go ahead."
