Make your way to the designated coordinates.
There is two places where you can park your car. One involves some uphill walk along a service road but not too much of a climb. This starting point is next to a cemetery located at N 50° 18.078' E 8° 16.563'. You can also park up un the hill near a restaurant. This parking lot is located at N 50° 17.992' E 8° 17.802'.
Approach the cache coordinates. You should stand in front of a church (open for visits on Sundays and Germany National Holidays between May and September from 2:00 PM till 5:00 PM).
There is a sign on the right side of the church door (on the outside wall of the church). Is has a total of five numbers on it. The first number is an elevation, the following four are year numbers.
In order to get the next set of coordinates, you will have to obtain the results of two different calculations.
Substract the 3rd number from the 5th number. Divide by 10. Add 1. This is result A. Now Divide the second number from the sign by 32 and add 0.4375 to that. This is Result B. Now Substract Result A from the North Coordinates of the first waypoint and Substract Result B from the East Coordinates of the first Waypoint (Purely as an example let's say Result A was 120 and Result B was 63 - Your new Waypoint would be N 50° 18.453' - 120 = N 50° 18.333' and E 8° 17.149' - 63 = E 8° 17.086').
This is Wapoint Compass 1
Go to waypoint Compass 1 and take out your compass. Count the number of benches between 40 degrees and 60 degrees. This number is Result C. Result D is calculated as follows: Add the 3rd and 4th number from the sign. Substract the 2nd number from the sign - This is your interim value. Multiply the first number from the sign with the number of benches (Result C). Substract that number from the interim value. Now substract 900 from that number. This is Result D.
Add Result C to the North Coordinates of Waypoint Compass 1 and add Result D to the East Coordinates of Compass 1. This gives you the Coordinates of Waypoint Compass 2.
Proceed to waypoint Compass 2. Look into a south-east direction. There is a Mountaintop with a tower on it. Get an exact bearing for that tower. Now the last part of calculations for the Cache location:
Substract Result C (= Number of benches) from Result D. Add this to the North Coordinates of Waypoint Compass 2. Now take the compass bearing and round down to the next tenth (again, just for example you took a bearing of 237 degrees - rounded down to the next tenth this equals 230). As a check, this number is evenly divisable by 4. Now add Result A and Result C to the rounded down compass bearing. Add this number to the East Coordinates of Waypoint Compass 2 and off you go towards the cache.
The Cache is in a round Tupperware container packed in a red and white plastic bag.
Corrected two minor mistakes Gerhard pointed out - Thank you for that bit of information and congratulations on being #1 on this cache !
A note on all the calculations that you are doing for this cache (Thanks Bob for pointing this out): All values and calculations on locations are to be made as if there were no decimal points in the WGS84 coordinates. What this means is that if you somewhere within the calculations end up with a number of 67, this is actually 0° 0.067'. Respectively, a value of 5 would be 0° 0.005' and a value of 231 would be read as 0° 0.231'
During winter, the seats and back support of some of the benches will not be there as they are made from wood. However, you will be able to determine the number of benches at waypoint Compass 1 by looking for the concrete support posts for those benches (2 per bench)
