My wonderful mother has been visiting for the last week and today we took an architectural tour of the city by boat.  I've been on one before, which I thought was great, but this one turned out even better.  We bought tickets from Shoreline Sightseeing, which turned out to be the same tour I had taken with another company a few months ago, but the tour guide today made all the difference.  Here's a link to the pictures in the photo section and a link to a video of the end of our tour guide's very talented performance.
