Revisiting Europe: Austria

Remembering from 2011: You can be sure that in Austria we sang plenty of Sound of Music songs.  I remember Esther and I hopping up and down some stairs near this unicorn belting out, "Doe!  A dear, a female dear."  It was also some anniversary for Mozart, so outside his home locals were passing out free chocolate balls with his face on it.  We went inside and saw a violin he owned which the violinists in our group went nuts over.

We took a tiny incline up to some castle which I thoroughly explored, but now don't remember

Except that I buildered its walls as well

Back down the incline!
