Surely Not More Window Cleaning

wpid7989-C59F9748.jpgI imagine you are wondering how many posts I can get out of the theme of window cleaning.  Well, here comes another one.  I think this will be the last one though, not least given our departure from Chicago.  This time I found myself looking down as a couple of guys were heading out over the edge of the building roof to clean another line of windows.  Watching people descend the side of the building is one thing but the first step over the edge always seems more precarious.
