While visiting friends we did a cache check and found the cache we had nearby was gone.
As it is a pleasant spot, we decided it was worth replacing. The replacement is a simple multi in a different spot. The original was at the seat which we were told was going to be removed but is still there so a useful spot to fill in the log.
At the waypoint you can find a 5 digit number. Add the first 4 digits and call the sum A. Over the road there are 2 letterboxes next to each other. Find the difference between the 2 house numbers and call this B.
Add B to the decimal part of the Waypoint South coordinate, and add A to the decimal part of the East coordinate.
This gives the coordinates you need to find the small cache.
