Paris Paris 
The first thing we did in Paris was go on a Paris At Night tour. Most of the major structures are all lit up. Here the Eiffel Tower is displaying a countdown to the year or Jubilee 2000. There were 486 days left.
Bob had a lot of fun pointing out the potential structural problems with the Eiffel Tower. Here he's examining all the rivets.
Notre Dame, like many other churches in Europe, was being restored for the Jubilee 2000. The inside was still beautiful, though, especially the windows.
One of our favorite places in Paris was the Pantheon. Here is the original Focault's Pendulum, where he proved the Earth does indeed rotate. Downstairs many famous French are buried, such as Voltaire, Victor Hugo, Lagrange (only the engineers will appreciate this one), and most recently, Marie Curie, who is the only woman buried there because of her own accomplishments.
Here's the controversial entrance to the Louvre. This picture was taken from inside the Louvre. I have to say it didn't really seem to fit in with the rest of the architecture, but that wasn't something I really cared about. I just wanted to wander around inside. There were so many things to see, and like I was told it would take days if not weeks to see it all. We saw the highlights - the Mona Lisa and Venis de Milo, among others - and enjoyed a lot of beautiful art and artifacts.
One of the things we found most humorous were the cars (except when we were trying to cross an intersection - there's no such thing as a pedestrian right-of-way in Paris). They were all so tiny. Here Bob's standing next to a Mercedes!
