Okay here is your back up.
I spent 2 months backpacking in europe throughout may, june and into july. And one of my pet peeves while touring throught out was the MASSIVE amount of graffiti. Now albeit, im from Canada, which doenst mean that were not immune to grafiti here but its pretty lo key, alot of volunteer teams help to keep it down to a minimum. However when we got of the plane in Copenhagen and took the airport express train you could see the graffiti along the tracks for MILES AND MILES (err kilometers and kilometers!) heh... it was pretty sad. The train station in Copenhagen, built in like 1878 or some such time period had very large quanties of graffiti all over it, it was a shame to see such an old and cool looking building "pillaged" in such a matter.
It only got worse as I headed south. One glimmmer of hope was in Barcelona, not much there, especially not on the metro, in fact it had one of the nicer metro systems (air conditioned) of all the cities i attended. Not really crowded either and only 3 mins from my hostel to the beach!
Berlin was bad in some places, but other places okay.... rome had some nasty stuff in the ancient city, and there was some inside the colliseum...
So yes... i did see the graffiti, and lots of it.
