I wouldn't want to leave it the same place, out of sight, for much time. Not with all those expensive components hanging from it. Not if it were in my cubicle, office, or the security office. Leaving something like the bike the OP posted in Portland OR out of sight even briefly is inviting trouble.

I once lost my roof rack bike tray while parked in front of a bike manufacturer's offices. Same thing. Everyone knows the car and walks around with allen keys in their pockets. Haha.
