Grafitti Maniacs

Every morning I wake up early and ride my bike.
Every day I rush by a narrow path surrounded by factories, where grafitti artists leave examples of their skills. Some of them are disturbing, others are really beautiful...
Every week, the drawings are different. Guess they make them hiding in the middle of the night.

* Thanks very much to all of you guys for the comments on my 200th blip. It's so nice to have so many of you so close... :)
