Oh - and at long last I actually took a photo from one of the two "sweet spots" of St. Peter's Square... Many of you may know about (or have experienced!) this phenomenon, but for those who don't - basically, there are two spots where you can stand in St. Peter's square and look at the columns and have them "line up" perfectly so that you only see "one" column in a row. They are not really labeled as such, just two inlaid marble disks in the pavement on either side of the obelisk (between the obelisk and the fountains). Cool, 'eh?
