Here we are at Terminal 2A at Charles de Gaulle Airport in Paris.

A view of the terminal.

The architecturally bizarre train station at the airport.

Some planes at Charles de Gaulle.

People and stuff in the terminal at Charles de Gaulle.

Eric waiting for the train to Brussels.

The first picture of my feet, taken while waiting for the train. That's the only bag I brought. It was heavier than it looks.

Waiting for the train.

Not many people were taking the high speed train from Paris to Brussels.

Here we are in Brussels.

Now to take the Metro into the city center. M is for Metro!

Finally walking around a city in Europe after quite a number of hours traveling.

Cars and buses parked in Brussels. The tour buses are a good indication that we're near something important.

Such as this, which I assume is a church. We didn't go in.

A view up the street adjacent to the church.

A guy named Kuipers invented topological maps, which are the basis for my research. Thanks!

A creepy-looking statue in Brussels.

A busy shopping area in downtown Brussels.

The main square in Brussels.

One of the buildings on the main square in Brussels.

More of the main square. They were setting up for some sort of concert.

Still more of the main square.

Another typically European street in Brussels.

Then it rained, and we got wet. Here, Eric is eating lunch under the shelter of an EU government building. Fanta is good.

And there I am, also eating lunch. Fanta not pictured, but present.

Eric, damp, tired, and on the subway in Brussels.

After that we took a series of trains to get to Zeist, Netherlands, where the WAFR conference was to be held in Hotel Figi, pictured here.

Here is my room in Hotel Figi. I didn't take too many other pictures during the conference.

Here is one, though, of me after the first day of talks.

The second day, there was a dinner in a nearby mansion. Here are some conference attendees walking there.

The street leading to the mansion.

There it is, up ahead.

And back the other way, the direction we came from. Zeist is a relatively quiet city of 50,000.

The mansion, with conference attendees wandering along.

Another view.

There was this moat surrounding the mansion. More on that later.

The mansion was quite nice inside. We wandered around.

Another room in the mansion before dinner.

People admiring the mansion before dinner.
