Nice photostory!
Vienna is such a beautiful city. Too bad I was there only once and only for a day. It is so close to the place I live (Ljubljana), so I will have to revisit soon. Thanks for reminding me about it. Maybe this year will be the right one to visit it. I know that zoo there is fantastic as well...
Thank you @crazy-andy. I think that Zoo is somewhere around Schoenbrunn, and I know that there is a great Botanical garden too. But on the last day, I was a little late to visit a house with butterflies-"Schmetterlinghaus" in the center, in the park, near the Mozart monument. I believe I would have something to photograph there. I have to go again soon.:)
