As you see, this is a mystery cache. Thus on the given
coordinates you won't find a thing (at least - not the container
for this cache, maybe somebody has put another cache there, I
seriously have no idea). The real coordinates for THIS cache are
56° __.___ E 023° __.___.
To solve the mystery and to understand the story behind this
cache (which I can't tell you, or I would spoil the mystery), you
are recommended to watch the 1987 Latvian animated film
Brunurupuci" (Tortoises) directed by Ansis Berzins. After you
have watched the film - take a look at the photo provided below,
maybe you can see the coordinates in it (they are written on the
picture).
A bit more about the cache - it salutes the Latvian tradition
of extreme road crossing and nighty walks on the highway.
The cache location has a very strong connection with this
tradition.
P.S. No geochecker is given: you will either see the
coordinates or you wont. You can also try to look for a "magic-eye"
3D effect in the picture but I'm afraid that it is not there. Still
- if it helps you to find the cache or if you just like staring at
pictures - you're welcome to do it.
Here's the picture:
