Please note that this is a needlessly complicated cache ;)
Stage 1. Collecting Data:
Special equipment needed: a 2-Euro coin (don´t worry, you don´t have to spend it)
The coordinates lead you to the beginning of the Paniglgasse.
In the Paniglgasse, there is a shop where a number of animals of the same species serve as mascots (I strongly doubt that these animals are very happy to serve as a mascot for this particular place)
(The number of animals – 1) is X.
Your next stop is the main building of the Technical University of Vienna at
N 48° 11.949
E 16° 22.203
On the side looking towards the Resslpark there are eight busts for distinguished professors.
One can help you find the cache. The follwing statement will help you find him:
(Hint: A “!” means a logical NOT, "&&" means a logical AND)
Once you found the correct gentleman take the last two digits of the first two numbers and add them.
Write down the result as Y.
(Hint: If the numbers on the bust were 1910 and 1956, Y would be 66)
Finally you´ll have to enter the Library of the Technical University at
N 48° 11.950
E 016° 22.067
(for opening hours see tuwien oeffnungszeiten bibliothek ).
You may not carry any bags into the library, so use your special equipment to store your bags and coats inside one of the lockers. Just remember to take your cache printout and a pen with you.
Go up to floor X and find the book with the following code “(The first X letters of the saint of dragonkillers name) (The first X digits of Pi)”
This book has several volumes – the volume you are looking for is X-1.
Find item (1800+Y-1) "/" (X*2) (Note that the “/” here is not a mathematical operator) and read the description carefully. At the beginning of an earlier chapter there is a simple map that should make navigating easier. Since this book is older than I am, the inn in the description is no longer there. Please note that you won't get any coordinates.
Since this is a library book there is always the chance that somebody borrowed this book (for some reason that’s seldom the case) – if the book is not there, or if you want to check your findings before you go for the cache, try this URL.
A note to English speaking visitors – While there isn´t much text you´ll have to read, some understanding of German is necessary. If you need a translation mail me.
Stage 2: Some fieldwork.
A flashlight could be useful
You can reach the area of the cache in about 40 min using public transport or your car.
Once there walk about 15 min to the cache location on a good path. On the last 50m to the cache stay on the edge of the meadow.
The cache is hidden behinde some stones on the left hand side of the objects entrance area.
If you want to check your solution online, but don´t have time to go home, look for Internetcafes or WLAN Hotspots in Vienna (or just use your fancy smartphone).
