Wife and I happen to be walking by and was curious what was happening inside this big Square that night so we got in line right before it got super long and got in before they stopped allowing people in. It was actually so much fun. They had the Olympics playing on three different huge screens too.
We were dancing it up like we were young again. We're in our 40s now. My wife would have never agreed to do that unless it was just a spontaneous thing like that and it turned out to be one of the highlights of our trip.
