Ahhh yeahhh.... I'm super jealous right now. I got to go to go back to Scotland & Ireland in 2009 but it was way to quick of a trip and I so wanted to go back to Spain and France (actually everywhere I traveled while I was living in Scotland).... I would have a whole different perspective, respect and appreciation for it all now, vs when I was 20 (not that I didn't appreciate it then, but the appreciation would be much greater now....oh and I wouldn't have spent our two days in Barcelona purely partying at night and sleeping in the day). Even after being mugged (I guess since we stupidly fought back and ran and they didn't end up getting anything it woudl actually be called an attempted mugging) I still loved that city (just wear a money belt )!
Enjoy!!
