Thank you for you entry. I Like the abstract nature of the logo.
Could you look at the Contest Attachments file LogoPT80.jpg and PRESIDIO_logo.jpg? Your entry is similar to those and I would like to see if you could enhance your entry by using the shape of the building and windows in LogoPT08.jpg and bring the subtle 3D effect of PRESIDIO_logo.jpg.
#74 - simple, strong, scalable and easily readable at all sizes, portable across media and colorways - definitely has a pleasing 'mission' feel to it...
