It was fun, and I met some new friends there too (to the right, Julian and Rupert).
After seeing this small portion of Austria, I realize that the real star of The Sound of Music was Austria itself. You can't visit and not feel that had that film not been set in Austria, it would've been less. It also helps you understand the characters better. George Von Trapp was intensely loyal to Austria, and the Anschluss (Nazi takeover of Austria) took what was his life, the other part having been lost when his beloved first wife Agathe died of scarlet fever in 1922.
Edelweiss, my favorite song in the film, is not an Austrian Folk song, but was written for the film. Edelweiss was a tiny white flower that only grew up in the mountains, in a cold, dry climate with bright sunlight (I still have some edelweiss seeds but have yet to find how to replicate that climate).
