I have never been there.
Though a few years back i was supposed to meet up with some online friends from East Europe, and we were going to go together. Since i had experience hitchiking across Europe, they wanted to try to Hitchhike to Barcelona and we would go from there.
So i flew to Barcelona, and sat at the fckin airport for 3 days waiting for the guys. 3 Days later, turns out they never even left the house! They were too scared to make the journey.
So yeah.
