The air zoo part two

A few days ago on Skype, Uncle Jeff mentioned Carsten's visit to the Air Zoo as a conversation starter.  Apparently when Jeff asks his son (just a few weeks old than Carsten) about his visit to the Air Zoo, Zachary says "Went up in an airplane. Went down" and that's the end of it.  This was no the case for Carsten.  For around the next hour, we heard variations on the following theme:

C: "Air Zoo!  Wanna go to the Air Zoo!"

A: "The Air Zoo is too far away. We can't go right now."

C: "Air Zoo too far... (furrowed eyebrows)" or...

C: "Air Zoo in America. Too far."

Natalie tried to distract Carsten by mentioning the fun things we get to do here - visiting the Flughafen, HB, riding the funicular ("the railroad train" to Carsten).  The resulting conversation went something like this:

N: "The Air Zoo is in America, it is too far away to visit. But we get to do lots of fun things here in Switzerland!"

C: "Wanna ride the railroad train!"

A: "It is dark. We aren't going to ride the railroad train tonight. Maybe we can go tomorrow."

C:" Wanna go to the Air Zoo! Air Zoo too far!"

The next day, we tried to talk about this experience on skype in a round about way.  Carsten was playing in the other part of the room, and we said something like: "There is a museum for airborne devices in a town near battle creek.  Jeff mentioned it yesterday and then..." at which point Carsten ran over and said "Air Zoo! Go to the Air Zoo!"  I'm not sure how he knew that is what we were talking about, but he seemed to know.

This morning, we didn't hear as much about the Air Zoo. But whenever Carsten was feeling bored, he would go to the window, look intensely up the hill and say "Air Zoo too far..."
