As I walked from the third floor down to the first floor, I glanced down at the next lower flight of stairs and saw a raccoon ambling down! I quickly left my bag on the ground, grabbed my iPad out of it and went down to the next level below and found him. He was walking back and forth along this low wall, every now & then looking WAY over the edge of the wall obviously trying to figure out how to get out of there. A co-worker that I told about seeing him that morning saw the same guy that evening (again on the stairs) as she was departing for the day. So as not to walk right next to him on the stairs, she opted to walk down the sloped drive area that vehicles use to get from one floor to the next.
