The story of this cache goes a way back when I was very young. I would go, with my family, by bike through our field in Bistrinci and we would stop at this place to rest, and to fish. As I grove up the place used to be night gatherings of my friends and we would sit by the fire and bake corn, and tell each other scary stories. We were exactly where the cache is hidden. On a bright sunny day you will have a beautiful scenic view all around. Feel free to just sit and rest, and listen to the birds.
The given coordinates are not final. To solve the final coordinates you need to go to the waypoint (Starting point) and write down the year beneath the cross. Year has four digits in the form of ABCD what you will use to calculate final coordinates of the cache. Also, this waypoint is the best way to come to this cache.
The formula for the final coordinates:
XXX = (C-D)*(B-A)-D*A+C*D*B-(A+B+C-D)
YYY = B*(C+A*C)+B*A-(B-D+A)+D*(B*C+A)
When you calculate the values then enter as followed to find out the final coordinates:
N 45º 41.XXX
E 18º 22.YYY
