Europe is generally safe, the only spots I felt even remotely sketched out in were Amsterdam & Brussels...
That is, until I went to Barcelona.
I was there for 8 days, and every day, somebody tried to rob me.. be it gypsies, pickpockets or thugs. I don't know what it was. I'm a big guy, and I was with a lot of friends, we are usually the last guys they target. But it happened, every day.
They are still pussies, all you have to do is get in their face and threaten to smash the shit out them and they run away tail between their legs, but still... watch your back.
I was amazed at one thing though: I was riding the subway during rush hour, the train is full of business commuters, and this raggity ass couple gets on, sits down, and proceeds to start smoking heroin. Nobody even glanced at them, they obviously did not give a fuck what anyone else thought either. I was just staring in disbelief and chuckling.
