Venice
I thought I wouldn't like it, but I was wrong. Yup, my one wrong for the year, you heard it here.
It was the annual Regatta, the historical parade of gondolas and thank god, they shut down the main canal so the tourists from World-o-Ships can't get in. So it is very few tourists and all locals.
We found a spot near the canal and watched the parade. It was about 15 minutes, but worth it.
