For a gorgeous introduction to nights and Barcelona, it doesn’t get much better than this.  If you come early enough, you can add a dip in the small pool to the night’s festivities.  Barring that, do like I did, bring some great friends, order from the gintonic menu, and forget that you’ve ever heard of the word “problem” – surely some form of rare rodent that lurks only in the caverns between the rooftops – only clear skies and bright hopes can you see!
