After having checked-in at one of the many hotels on the Las Vegas Boulevard (also known as "the Strip"),
I turned my eyes to the middle floors and saw this kind of SpiderMan bouncing from window
to window with an incredible agility. It took him less than 5 seconds to clean one window,
the problem is that there were at least a thousand windows on that side of the building...

Taken with Nikon gear, 300mm and Velvia 50
(polarized a little bit to remove the reflections from the windows)
