The OPUBCO building at Britton and Broadway has 12 floors, give or take a basement. The window washers usually take a few days to get all sides of the building.
The other day, I took this photo with the iPhone as the guy cleaned the window to my office. Windows are tinted at OPUBCO so he couldn’t really see in.
I couldn’t do this job. Looks hard and one wrong slip with that rope would be serious bad news. This view is from seven floors up.
