Annette, our daughters and I just spent a week in Flachau, Austria with Annette’s family. Flachau is not far from the Austrian city of Graz, where Annette lived until she was twelve years old.

A few days later I was back at the facility, asking for a tour.  What follows are notes and photos from that tour.
